SERIES 02 — THE SCIENCE OF COLOR
Looking at color not only through perception, but through data.
When we look at someone’s skin, we naturally use words such as:
“bright,”
“reddish,”
“yellow-toned,”
or “deep.”
These descriptions are not necessarily wrong.
The human eye is remarkably capable of noticing differences in skin color.
But seeing skin color and measuring skin color are not quite the same thing.
To understand personal color more objectively, it helps to first understand what each of these approaches can—and cannot—tell us.
Skin Color Is First Something We Perceive
Once color reaches our eyes, it is no longer experienced as an isolated physical value.
The light in the room, surrounding colors, shadows across the face, facial contours, hair, eyes, and lips can all influence the way skin appears.
The same person may look different when wearing white than when wearing a saturated color.
Skin can also appear different in daylight, warm indoor lighting, or cooler artificial light.
As we explored earlier in this series, human vision does not perceive colors in complete isolation.
We see them in relation to their surroundings.
Looking at skin, therefore, means observing more than a single patch of color.
It means perceiving a complex visual relationship across the entire face.
Why Measure Skin Color at All?
Visual observation provides valuable information.
But language based on perception can vary from one observer to another.
One person may describe a complexion as “light,” while another may consider it closer to medium.
The same is true for descriptions such as “reddish,” “yellowish,” or “muted.”
Without a shared reference, these words can mean slightly different things to different people.
Color measurement creates that reference.
Measuring color is not about forcing a subjective impression into a number.
It is about recording color characteristics under defined conditions so they can be compared more consistently.
What Does It Mean to Measure Skin Color?
When light reaches the skin, some wavelengths are absorbed while others are reflected.
Color-measurement instruments capture information from that reflected light and translate it into numerical color data.
This allows characteristics such as lightness and color direction to be recorded in a form that can be compared.
Instead of relying only on descriptions such as:
“a little brighter,”
“slightly red,”
or “more yellow,”
color can be represented through standardized numerical systems.
One widely used example is the CIE L*a*b* color space, which describes color through dimensions related to lightness and opposing color directions.
The important point, however, is not memorizing the numbers.
Numbers are another language for describing color.
They give us a reference through which different skin colors can be examined more consistently.
A Measurement Is Not the Absolute Truth About Someone’s Skin
A numerical reading should not be treated as the single definitive answer to a person’s skin color.
Every measurement is obtained under a particular method and set of conditions.
The area of skin being measured, the measurement procedure, and the condition of the skin surface can all matter when interpreting the result.
More importantly, personal color analysis asks a larger question.
We are not interested only in the color of the skin by itself.
We want to understand what happens to the face when another color is placed beside it.
That is why a skin-color measurement alone cannot determine every color that will look harmonious on a person.
The Eye and the Instrument Answer Different Questions
Visual observation and color measurement do not need to compete with one another.
They provide different types of information.
The eye sees relationships.
It observes how the face changes beside a color—how the complexion appears, how contrast shifts, and how the overall facial impression changes.
Measurement creates a reference.
It records characteristics of the skin that can be compared across measurements and expressed beyond subjective descriptions.
For personal color analysis, objectivity does not mean replacing observation with numbers.
Nor does it mean ignoring measurement and relying entirely on intuition.
It means understanding the distinction between what can be observed and what can be measured—and interpreting the two together.
Why COCORY Looks at Skin Color as Data
At COCORY Color, we do not define people through a single label such as “warm” or “cool.”
Skin varies in lightness and color direction, while every face also contains its own combination of skin, lips, eyes, hair, contrast, and structure.
To create a more consistent reference for observing those differences, COCORY uses its proprietary CUBE skin colorimeter as part of the analysis process.
The purpose of CUBE is not to reduce a person to a number.
It provides a measurable reference for characteristics that might otherwise be described only through visual impressions.
Those measurements can then be considered alongside what happens when actual colors are compared around the face.
Data and visual observation become more meaningful when they are interpreted together.
Data Is the Beginning of Analysis, Not the Conclusion
The purpose of using data in personal color analysis is not to classify people faster.
It is to describe differences more precisely.
Instead of stopping at:
“this skin looks slightly brighter,”
or
“this complexion seems a little more red,”
measurement allows us to ask:
How different is it?
In which direction?
And how might that difference interact with color?
The eye and the numbers are not trying to replace one another.
The eye tells us how a person appears.
Measurement helps us record what we are observing.
For COCORY, meaningful color analysis begins where these two forms of information meet.

2-2. How to Read Skin Lightness, Redness, and Yellowness in Numbers
What do the numbers used to describe skin color actually mean?
In the next journal, we look more closely at L*, a*, and b*—and how numerical color data connects back to the characteristics we see in real skin.
EDITORIAL NOTE
COCORY JOURNAL does not approach personal color as a collection of fixed types or passing trends.
It records COCORY Color’s research and perspective on how color interacts with people, how faces and skin respond to surrounding colors, and how individual characteristics can be observed and analyzed through clearer standards.
