Editing Complementary colors (section)

==Practical applications==
The use of complementary colors is an important aspect of [[aesthetic]]ally pleasing art and graphic design. This also extends to other fields such as contrasting colors in [[logo]]s and [[retailing|retail display]]. When placed next to each other, complements make each other appear brighter.

Complementary colors also have more practical uses. Because orange and blue are complementary colors, life rafts and life vests are traditionally orange, to provide the highest contrast and visibility when seen from ships or aircraft over the ocean.

Red and cyan glasses are used in the [[anaglyph 3D]] system to properly visualise the [[stereoscopy|stereoscopic]] images produced.
