Do you mean lookup the color name based on the RGB value?
In general this is ill-defined because there are only about 1000 colors
defined in rgb.txt but there are 256^6 possible RGB combinations, assuming
16 bit depth.

What you can do is program a best approximation in some sense, for example,
least-square approximation.  The classic program for that is xcolorsel;
I have recently written a gtk 2.x act-alike called gcolorsel:

(the .orig. is because it is part of a Debian source package, together with
the .dsc and .diff.gz files at the same location)
