WHITENESS FORMULA BASED ON CIECAM02 AND THEIR TEXTILE APPLICATION

Whiteness is an attribute of colors of high luminous reflectance and low purity situated in a relatively narrow region of the color space. The evaluation of whiteness of a product is dependent from the materials and the application it is used in. The most common acceptable formula for evaluation of white samples is the CIE whiteness index. The performance of the CIE whiteness formula is focused on D65 illuminant and narrow region of color space correl ate not well under other conditions. Whiteness Vik-Vikova WVV whiteness formula was published on CIE Midterm meeting on Jeju Island, Korea 2017 is based on CIECAM02 color appearance model, respectively on its approximately uniform version called as CIECAM02UCS. A visual assessment study of the selected samples was carried out in order to relate the influence of the tint to perceive white. The results show that the new whiteness formula outperform other whiteness formulae in case of samples on the border of CIE Whiteness formula limits.
