* Do not use color  as primary method of communication.

==Purpose==
Color is a basal quality in human perception. Color can be used for communication, it is a very efficient way to direct attention, and significance can assigned to an object with color. However, color is a historical and cultural phenomenon, and is subject of continuous aesthetical changes. Furthermore, it should be taken into consideration that a rather high percentage of population has a perception disorder ranging from difficulties to discriminate between red and green to complete color blindness.

==Guidelines==
* Choose colors by selecting the appropriate theme color or system color.
* Never use color as a primary method of communication, but as a secondary method to reinforce meaning visually.
* Make foreground color contrasting to background.
* Consider accessibility for users with color vision deficiency (~5% population).
==Implementation==
