Title
Color change based on lower chroma of poster colors
배용진 Bae Yong-jin , 권오현 Kwon O-hyun
Abstract
`Color-mixing specialists` who are professionals in mixing colors have been working in the industrial fields for a long time and `naked eye-oriented color-mixing` has been part of the certification test to be a `colorist (industrial)` conducted by Human Resources Development Service of Korea since 2002. Adjustment of chroma through naked eye-oriented color-mixing is based on mixing chromatic and achromatic colors, and beginners have often failed in choosing the right colors of colorants, since they are unaware that colors tend to change as chroma changes. For example, when mixing colors of 1GY~5GY, beginners usually fail by selecting light green. It is because they are not aware that mixture of lemon yellow and achromatic colors result in light green, although they should choose lemon yellow while mixing colors of 1GY~5GY. Therefore, this study is aimed at allowing color-mixing beginners and colorist test-takers to choose accurate colors with naked eyes by presenting color changes based on reduction in chroma (desaturation) and helping them to predict them. In order to validate the experimental results, a survey was done on 124 design majors who were taking chromatology as to whether the degree of color changes based on desaturation affect their color selection while mixing colors, and they were less likely to choose correct colors as the color changes became greater. Hopefully. this study will allow color-mixing beginners and colorist test-takers to choose correct colors while mixing colors with naked eyes, by presenting colors that greatly change in accordance with chroma and helping them to be aware of them.
