This represents a wealth of similar color spaces, alternatives include HSI
(intensity), HSV (value), HCI (chroma/colorfulness/intensity), HVC, TSD
(hue saturation and darkness) etc etc. All these color spaces are non-
linear transforms from RGB and thus, device dependent, non-linear but
very intuitive. In addition the seperation of the luminance component has
advantages in image processing and other applications. (But take care,
the complete isolation of the separate components will require a space
optimised for your device. See later notes on CIE color spaces)
------------------------------------------------------------------------
It seems that you need to characterize a particular device (measure its
properties), and then determine how HVC values can be converted to RGB
values. For example, you could prepare a table of corresponding values.
Check with the manufacturer of your device (e.g., Sony for a Sony video
monitor). Color matching systems usually have conversion tables for the
color models and devices they support.
