Pigments selectively absorb wavelengths of light. When white light strikes a pigment molecule, there are different processes that can lead to absorption. Conjugated systems of double bonds absorb light in some organic pigments. Inorganic pigments may absorb light by electron transfer. For example, vermilion absorbs light, transferring an electron from the Read more…
A pigment is a substance that appears a certain color because it selectively absorbs wavelength of light. While many materials possess this property, pigments with practical applications are stable at normal temperatures and have a high tinting strength so only a small amount is needed to see the color when it’s used Read more…
