Abstract. This paper, which is based on the research in the personal color diagnoses system, uses
the fuzzy logic and fuzzy inference rule to improve the personal color selection method of the
existing personal color system and to get more objective and reliable result for personal color. We
propose the method which constructs more systematic color selection system using personal color
database and fuzzy logic.
Introduction
The personal color system is the color diagnosis system which raise the added value of the image
through the production of the image that oneself pursues with diagnoses the accord color which is
most matched with the unique body color that the individual own.
Recently, a lot of interest is being concentrated on the personal color diagnosis system which
analysis and diagnoses a color based on the personal color theory. But the chromatic diagnostic
system which is used currently, classify a color type with only the skin condition mainly, so the
judgment ground and accuracy could be a little insufficient. In this research, it proposes more
precise chromatic diagnosis rule which considered sex condition, psychological condition and body
condition with using of fuzzy rule as the after treatment to improve the problem like this.
This research divides 4 seasonal types of body color which each person keeps through the
experiment which applies a fuzzy theory and a fuzzy inference, and gets objective data with
calculates a membership about each value of R, G, B, therefore it did the more scientific and
systematic personal color diagnosis simulation.
The composition of this paper is same as below. In chapters II, it indicates the relation research
about personal color and fuzzy theory, an explanation and problem about the diagnostic system
which is using at present, In chapters III, there is the test through the simulation of the personal
color diagnostic system which uses the fuzzy logic that is embodied in this paper, In chapters IV, it
is finished with the conclusion and hereafter research.
Preceding Research
Personal Color
The personal color system as the study of systematization already from the West Europe long time
ago, was introduced in Japan since about 20 years [6]. But In our country, recently the research to
be advanced by some specialists is tendency of revitalization with supplying in rapid pace as the
interest of multitude is concentrated. The historical investigation to arranges the branch of the
theory which accomplishes a foundation of the personal color system, is same as below [3][4].
Johannes Itten, the professor, and the scholar of the color of the Bauhaus, as the synthetic
moulding school in Germany, has found that the preference color of the students is related to their
unique color, namely, the color of skin, hair, eyes etc. as their own, and paid attention to the
relationship between the appearance and the subjective view of chromatic in 1928, It is becoming
known as the beginning of color analysis. After that, Carol Jackson of Canada, classifies the image
of the human being with the 4 units of seasonal type, it is announced with the book as the “Color
me beautiful”(1980), with this, the personal color system theories were subdivided in the United
States, Europe, Japan, etc.
Faber Biren, the color psychological scholar of the world-wide authority, who's evaluated highly with
the achievement which introduces the use of the color based on a chromatic theory in the society life,
has defined that every colors have warm color and cold color in each color as the other theory, not the
existing color classification of the warm color system and cold color system. Also, Robert Dorr (1905 1980), the scholar of color of the United States, announced the "Color key system" of Color Keys basic
color which is based on the theory that the skin color of the human being has Tone of two colors,
namely, warm color and cold color, and asserted that the blue under tone and yellow under tone by
classified became harmonize between the color of same classification.
According to Bernice Kentner(1991), Hippcrates of 2400 years ago, classifies the characteristic
pattern (form) of the people with gloomy (winter), cold (summer), cheerful (spring), and hasty
(autumn), this is being applied in the character and psychological analysis in these days, and he
published "Color Me A Season" with connect the "characteristic theory" and the colors of human
relation [3][6].
Our human body show each different skin color like some people are yellow, another are more
red than the others, and some people are darker than the others etc. for effect of 3 kinds of pigments
like carotene, the hemoglobin and the melanin.
The personal color is decided with proper color which individual keeps, namely, the color of
skin, hair, eyes, etc. among those 3 elements, the skin color became the most important element.
(Table 1, explains the point of reference like this). The personal color is made by the 4 seasonal
color analysis as the spring, summer, autumn, winter which is harmonized with each personal
proper body color after diagnoses the proper color which individuals were born, especially it
classifies 4 seasonal color types with dividing color of skin, hair, eyes. (Table 2, explains the point
of reference like this).
All of colors could be divided with cold color and warm color, the basic background color of
pattern of spring, autumn is yellow and gold color as warm color, it has the feeling of movement,
clearness, deepness, elegant, and the basic background color of pattern of summer, winter is blue,
black color, and it has the images of soft, thickness, romanticism, clearness, urban, dynamic image.

Warm, healthy, familiar image
The skin color of the human being is accomplished with 3 kinds of pigments, namely, melanin,
hemoglobin, and carotene, generally the black race has more melanin, the white race has more
hemoglobin, and the yellow race has more carotene contents compared to the other pigments, and
the thing that the each skin color is shown differently though same race is the result following to the
component ratio of these 3 kinds of pigments. Our skin could be divided in 2 types largely, as warm
type skin of ivory, yellow, copper color, and gold and cool type skin of white, pink, red, and blue.
Cool color means the color which includes white, blue, and black in every color. Especially the
color which includes white and blue is called summer type color and the color which includes blue
and black is called winter type color. Warm color is the color which includes yellow and gold in
every color. Especially the color which yellow is basic background color is called spring type color,
and yellow and gold become a basic background color that is called autumn color. Because of the
skin color of spring type people is yellowish, transparent and thin, it's the type which the spots like
freckle could be appeared in the face easily. The eyes color is yellowish; the hair wears the light
brown color. The image of the spring person is bright and vivid so there are many style which looks
younger than age and cute [9].
The skin color of summer type person is white and green light goes round or the pink light circles
round, and does not burn well in the sun and to be red. The eyes color is the soft brown, the hair is
the brown which wears gray and is a dry lackluster type. The image of summer type is somewhat
cold, romantic and feminine. The skin color of autumn type person is yellowish, lackluster and
white-livered. It's easy to be burn in the sun, the face color changes to brown easily. The hair is
lackluster dark brown, eyes color is umber which gives peaceful and fluffy. The image of the
autumn person is warm and soft which gives intimate and comfortable feeling, it has natural and
classic image. The skin color of the winter type person is cold and pale, the eyes and hair color is
deep gray-brown or black so it's contrasted with white skin and gives polished image. The image of
the winter person is cold and intense, keeps the intellectual impression.

Fuzzy Theory
Fuzzy is the theory which could appear fuzzy intellection of human being that couldn't divide with
only dichotomy in the computer with mathematical function, as compared with the logic circuits of
computer moves by the absolute standard like 0 and 1, this theory is the method which let the
computer executes the thought, studying, self-development, etc. that the intelligence of the human
being could do [1][2].
Fuzzy theory is proposed by Zadeh professor of the Berkeley university in the States, he has
constructed the basic of the fuzzy theory with announce the papers like 'Fuzzy Sets' 'Fuzzy
Algorithm"(1968) etc. on the 'Information & Control' as the world-wide magazine related to the
information and control at that time of 1965. Originally the professor, Zadeh proposed this theory to
make 'absolute assessment standard of beauty' with accurate the appearance of his wife in a true
number. After that, the professor Mamdani of Grate Britain applied a fuzzy theory to the pilot plant
of steam engine at the beginning, and executed successful experiment, and succeeded to the first
commercialization with applying the fuzzy control to the Cement Kiln process [7].
As the own academic society as 'International Fuzzy System Association: IFSA)' appears in
1985, the fuzzy theory develops more and it's being counted as the study which will lead the
computer theory of next generation with neural network theory at the present [8].
Experiment and Simulation
In this research, it calculated a membership degree about the each R.G.B value of skin color, hair
color, eye color, wrist color which decide 4 season types and defined a Fuzzy function, with
standing on those, it suggested more scientific and systemic diagnosis method with embodying a
Fuzzy basis personal color system.
Season Type
In the case of that the skin color, hair color, eye color, wrist color are each specific, the season types
are decided previously. It is expressed as total 12 dimension because the color feature space(feature
space) is expressed as third dimension(RGB) by 4 kinds of color.
ex) skin=(255,233,204), hair=(180,154,102),
eye=(126,93,50),wrist=(252,231,202)⇒(Spring)
The kinds of season types are classified and declared for spring, summer, autumn, winter.
Distance from Season Type
It calculates the distance in the feature space with the color of season types which defined in
advance and questioned color. For this, 256 units of samples of the season types which is suitable
for the body color. In the case of that the season types which defined in advance are over 2 units
when calculating a distance calculation, it could defines the distance from the most closer season
types as the distance of the season types in point.
Figure 1. Distance from Season Type.
Estimating Season Type for Query Color
It calculates a membership degree of each season types about the color in question in point with
calculating a color in question and each season types. I've planed the Fuzzy membership function
with using a principle that the distance of the color in question and the samples of specific season
types in the feature space closer, the membership degree will be increased.
Fuzzy membership function is used with fully-qualified the reciprocal number of the distance
with each season types to the sum of total reciprocal numbers. Also, it's set that could reduce the
actual condition which Fuzzy membership function lay stress upon one specific sample with setting
coefficient (α) which control a sensitivity.
In this research, the Fuzzy basis personal color system which drives in Windows XP Professional
Edition is embodied with using Microsoft Visual C # 2005 languages for testing.
If the user input his or her skin color, eye color, hair color, wrist color etc. and push the button,
then it show the season types which appeared user's personal color with calculating the membership
degree about each value of R.G.B which used the membership function, therefore, it could know the
convenient color diagnosis result of high reliability.

The selecting standard of color which fits image in point of each season types is same as below.
Namely, The horizontal axis showed a temperature feeling of color, the vertical axis showed a solid
or tender feeling of color and the each differences are divided for 6 phases.

Conclusion
This paper suggested that the method which diagnoses the original color types of each individual
more correctly with using the Fuzzy logic and Fuzzy illation rule based on the theory of the
personal color system. And it is offered that image of season types and the color which fit it thus, if
you use this in the real life, you'll raise the value added of the individual's image more highly.
As the research task in the future, if it considered that a mental state of each individual's or the
life style not only diagnose with just color of appearance like skin color in the personal color
diagnosis, and then the more perfect color diagnosis system which fits the demand of approached
sensitivity information time will be developed.
