The term "achromatic color" refers to colors that are devoid of any hue or saturation, such as black, white, and shades of gray. Antonyms for this term are chromatic colors - hues that contain color and are not black, white, or gray. These colors can be seen in the spectrum of light and are widely part of the color wheel. The most commonly known chromatic colors are red, yellow, blue, orange, green, and purple. They can be mixed to create a vast range of hues, saturation and luminosity. While achromatic colors evoke feelings of neutrality, calm and formality, chromatic colors have the power to elicit emotions and create an ambiance.
