Purple (or violet) sits at the edge of the visible spectrum, combining the calm of blue with the energy of red. Throughout history, purple has been associated with royalty, luxury, and creativity. In digital displays, purple is created by combining red and blue sub-pixels, making it useful for testing both color channels simultaneously.

Purple combines the alertness of blue with the warmth of red. Some people find it helps with creative tasks, though bright purple can be fatiguing over long periods.
