Color constancy refers to the ability to recognize the color of an object despite changes in lighting. It is the effect in which the perception of an object’s hue remains constant even when the wavelength distribution of the illumination is changed. Approximate color constancy means that our perception of hue usually changes a little when the illumination changes, though not as much as we might expect from the change in the wavelengths of light reaching the eye.
Color deficiency is a condition affecting people who see fewer colors than people with normal color vision and need to mix fewer wavelengths to match any other wavelength in the spectrum. Color deficiency is sometimes incorrectly called Color blindness.
Colostrum refers to a thin, yellowish fluid, high in protein and antibodies, secreted from the nipples at the end of pregnancy and during the first few days after delivery.
