What does Metamerism mean?

Hint: In order to answer this question, we will explain the whole concept of Metamerism and then we will go through the body design of metamerism also. And atlast we will describe the cause of Metamerism.

Complete answer:
When two colors appear to match under one lighting condition but not when the light changes, this is known as metamerism. Metameric matching is widespread in near-neutral colors like grays and whites, as well as dark colors like these. The range of probable metameric matches shrinks as colours get lighter or more intense.
Metamerism is a psychophysical phenomena that is usually misunderstood as "two samples that match when illuminated by one light source but do not match when lit by another light source."
Colors alter when viewed in different light sources, which is known as metamerism. The carpet, for example, was presented in a showroom lit by warm incandescent lighting before being installed in a chilly fluorescent-lighted office.
Metamerism is a body design in which similar body segments and organ systems are serially replicated one after the other in some animals. Metameres or somites are the terms for similar body segments. Metamerically segmented animals are those that have such characteristics.

Note:
To manage metamerism during color production, we need to know what causes it.
When a product is put together with multiple materials, metamerism is prevalent. This is a problem that automakers face on a regular basis. Despite the fact that the body paint is created with pigments that differ from those used on the bumpers and rearview mirrors, and the inside cloth is dyed with dyes that aren't even close to the fingerprints of the pigments used on the plastic dashboard, the assembled car has to match under virtually all types of illumination.
