Core color system for producing color, has color spaces, where additive color pattern has four additive primary colors in centre of spaces, and subtractive color pattern has four subtractive primary colors at boundary between spaces

摘要

The system has color spaces, where an additive color pattern has four additive primary colors in centre of the color spaces. A subtractive color pattern has four subtractive primary colors at a boundary between the color spaces. The color black is producible through absence of all spectral regions, and the color white is producible through presence of all spectral regions. The colors green, orange, purple and blue are utilized as the additive primary colors.
