Color (American English) or colour (Commonwealth English) is a property of light as seen by people. In Commonwealth English, it is spelled “colour” (notice the “U”), while in American English it is “color” (no “U”).
The following are the most common color names:
- Gray (American English)
- Grey (Commonwealth English)
- Navy blue
"Primary colours" can be mixed to make other colors. Red, yellow, and blue are the three traditional primary colors. The primary colors for television screens and computer monitors are red, green and blue. Printers and paints use magenta, yellow, and cyan as their primary colors; they may also use black. Sometimes this set of colours is simply called red, yellow, and blue.
When something has no color, it is transparent. An example is air.
The science of color is sometimes called chromatics, colorimetry, or simply colour science.
