The conventional color; referring to blood in which the amount of hemoglobin in the red blood cells is at an expected level: Dr. Swarez, the hematologist, was pleased with the normochromia of the patient under her care.

1. In photography, maintaining natural relations of light and shade; especially, by the use of films or plates treated to give correct values to the reds, greens, blues, and yellows.
2. Having normal staining characteristics; such as, orthochromatic film, a photographic film that responds to colors in their normal brightness as seen by the eye.
3. Relating to, or producing, true tone values of light and shade in a photograph that correspond to the tones in nature.

Descriptive of something that stains readily with acid dyes; relating to oxychromatin: Cell or tissue elements that are oxychromatic are those that have an affinity for acid dyes, such as eosin.

1. Showing different colors when viewed from different directions.

1. The property possessed by some crystals of exhibiting different colors, especially three different colors, when viewed along different axes.
2. The phenomenon of different colors appearing when certain crystals are viewed from different directions.
3. An optical phenomenon where due to double refraction of light by a colored gem or crystal, the light is divided into two paths which are polarized at a 90° angle to each other.

As the divided light follows different paths within the stone and are traveling at different speeds, they may have the result of differential selective absorption; therefore, when they leave the crystal they have different colors, making the stone appear to be of multiple colors.

Some stones show two colors or shades and are called dichroic, some show three and are trichroic. Gems are sometimes cut and set either to display pleochroism or to hide it, depending on the colors and their potential attractiveness.

The property possessed by some crystals of transmitting one color in one position and the complementary color in a position at right angles to the first; pleochromatism.

1. Exhibiting many colors.
