Hello all,
I have a jet colorbar appearing with my figure. I want to set the 'YTickLabels' at specified RGB values of the colorbar (i.e) at the points that bears the color with RGB value [0.3333 1 0.6667] in the colorbar i need to be named as 'A'.
Is there a way to do this???
Thanks in advance for the help.

Here is an example:
hSurf = surf(peaks);
hCbar = colorbar;
set(hCbar,'YTick',[-5 0.3 6],'YTickLabel',{'Blue','Green','Red'})
You will have to determine the y-values that correspond to the labels you want. For this, you should understand the different methods of colormapping ( direct vs. scaled ) and the axes CLim property. Here are links to some of the relevant documentation to help you get started:

Ah, I see I misunderstood the question above. I was thinking the reverse, of coloring the Y axis tick labels according to the color on the colorbar.

Unfortunately I don't think there's any way to do this, supported or unsupported.
EDIT: Nevermind, I misunderstood the question, see John's answer, I think that should get what you're going for.
