As primary‐shifts on LCDs is non‐negligible, primary‐invariance model, widely used to characterize the color reproduction on CRT monitors, can not be applied well on LCDs. To obtain average color difference of less than 3ΔE;* uv for LCDs, primary‐invariance forward model should be modified by at least a 3×9 regression analysis matrix. In backward model, polynomial regression method can transfer data in both RGB and XYZ domains. However, only in XYZ domain, desired colors can be reproduced sufficiently.
