I have written three online color calculators that may be of general
interest to the color community at large.
1) A general color conversion calculator that can convert freely among the
CIE representations (XYZ, xyY, Lab, LCHab, Luv, LCHuv), the Photoshop RGB
working spaces (about ten of them) and correlated color temperature. It
includes a couple different chromatic adaptation algorithms and several
different reference whites.
2) A GretagMacbeth ColorChecker chart calculator that performs spectral
calculations (i.e. no adaptation necessary) among the same color spaces
listed above. With it you can see what RGB values each patch should have WRT
each of the Photoshop working spaces.
3) A dot gain calculator.
These may be found in the "Color" section of my web site and require a
fairly recent Java enabled browser. Thanks to Bruce Fraser and Joseph
Holmes for their consent and assistance in implementing their custom RGB
working spaces, BruceRGB and Ekta Space PS5.
