I never claim to like any single colour.
It always has to be in contrast with something and depends upon the context.

For example in a GUI application, if I am making thin lines on black background, I would go with higher Luminance colours.
If I am making 2 large areas side-by-side, separated by colour, then I am most probably going with a very slight difference in Luminance.

Then it also depends upon the screen. I like amber lines on a black background, but have never seen a satisfactory amber on my LCD display. I have seen CRTs do that better. And the most satisfying amber I have seen is that of a CFL at night, where even the colour of the wall behind it, affected the impression (not a screen, but a lighting fixture), so essentially a gradient.
