Color Management System (CMS) Gamut Controls
Most displays provide color gamut controls, often called a Color Management System (CMS). Ideally, each primary and secondary color would have controls for:
- Saturation
- Hue
- Intensity
Some displays have the same adjustability through using Red, Green and Blue adjustments for each Primary and Secondary.
This is called 6-axis 3D CMS.
Overall differences
Errors are measured at dE values (typically dE2000, though there are other Delta E formulas that may be used). The overall dE value gives a good impression of the amount of error in the reproduction of a given color, but does not provide much information for how to correct those issues.
Error details
Calman shows where the errors are with the RGB Balance chart and with Deltas L,C, and H (Luminance, Color, and Hue) charts. Use the dE charts that conform to your CMS controls.
