Colour is a complicated subject. :) If you are able to use a device such as a colorimeter, you can write a program to measure the colour gamut of your monitor. Using this information, and assuming that your application outputs colours assuming a standard like sRGB, you can use the gamma table in X to map input colours to the appropriate ones for your monitor, and do something intelligent with ones outside of the gamut. That is, at least, one approach. I think the basic answer to your question is that X lets you set the colour ramps for each of R, G, B individually (see the 'xgamma' application) and this can be used for some colour correction work, but not all. Doing more would require gamut mapping by the application, and likely access to a colorimeter or knowing reasonable guesses for the phosphors in your monitor. -- Billy Biggs [EMAIL PROTECTED] _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
