Question

Actually wt is metamerism and how to identify it

Answer 1

Answer:

Metamerism is a phenomenon that occurs when two colors appear to match under one lighting condition, but not when the light changes. Metameric matches are quite common, especially in near neutral colors like grays, whites, and dark colors like these. As colors become lighter or more saturated, the range of possible metameric matches becomes smaller.

Explanation:

It can be detected through visual means, by using a light box or Colour Assessment Cabinet (CAC) and through digital means, using a spectrophotometer or DigiEye system, which can accurately measure colour and appearance digitally, helping predict metamerism when used in conjunction with recipe formulation software.
