LMS

A Trichromatic Color Space containing dimensions for:

• Excitation of the L-Cone
• Excitation of the M-Cone
• Excitation of the S-Cone

It is readily convertible to CIEXYZ Color Space, which can then be converted to other Color Spaces like RGB, HSL, etc.

Because of the overlap of cones in the Absorption Spectrum, some LMS values (e.g. Hyper-Green) are impossible to excite naturally. These are called Impossible Colors.
