Since colour influences product quality, safety and costs, consistency is important, establishing the need for international colour standards. Certified colour standards are composed of electrophotographic reflectance data that combines a master electronic standard and visual reference to ensure consistent colours across materials.
International Colour Standards
There are several colour standard charts for reference:
- RGB: The red, green, blue (RGB) colour standard is the colour display for LCD screens, CRT monitors and plasma displays.
- CMYK: The cyan, magenta, yellow, key (CMYK) colour standards are used for printing since the RGB standard cannot create black.
- Pantone: Pantone colour standards are vibrant, solid colours that can be converted to RGB or CMYK when necessary.
- USDA: USDA colour standards help agriculture professionals decide when produce should be picked and how it should be graded. Food processors also use these standards for food processing and packaging.
