ABSTRACT
A wide variety of colors leap into our eyes when we just look around. We are surrounded by an innite variety of colors in our daily lives. An average person can distinguish as many as 350,000 different colors, among which are 5000 distinguishable white colors, but the number of basic color terms is conned to not more than 11 basic expressions, regardless of cultures or languages [1]. However, unlike length or weight, there is no physical scale for measuring color, making it unlikely that everyone will answer in the same way when asked what a certain color is. For example, if we say “yellow butter” or “yellow cheddar” to people, each individual will imagine different yellow colors, because their color sensitivity and past experiences are bound to be different. This is the problem with color [2].
