Matrix1 Utility Plug-ins

Matrix1Util_23

This plug-in provides extra functions for dealing with RGB colours in both 32 and 16 bit colour depths.

It also provides functions for converting HSV, HSL, CMY and CMYK colour ranges to their equivalent RGB colours, and the packing & unpacking of those colours into a single DWORD value.

Differences between HSL and HSV include:
- In HSL, saturation ranges from full colour to grey based upon the luminance, while in HSV it goes from full colour to white.
- In HSL, the Luminance ranges from pure Black to pure White, while in HSV the Value goes from pure Black to full colour.

CMY and CMYK are subtractive colour spaces, rather than the additive spaces represented by RGB, HSL and HSV. In term of RGB colour:
- More Cyan means less Red
- More Magenta means less Green
- More Yellow means less Blue
