No rush. I won't touch the sidebar until I get yours back. There's plenty of other fish to fry so don't think you're holding me up at all. :-)
Bhoney :: Great question! Here it is plain and simple (if there is such a thing.. and if there is it's never following someone claiming plainness and simplicity).
On white backgrounds using light & bright colors has a very clean look to it. It is sharp and classy without being at all brash. Using none bright colors (like f00, 0f0, or 00f) is too strong and domineering on a neutral white background... so you go with fc0, or cf0, or c0f.
Now, to address the line green question. Certain very light colors look better than others. Almost assuredly the lighter reds look pink, and many people avoid pink unless they're deliberately trying for it (because it connotes too much). The lighter yellows often are too light, and when they're aren't too light they look dull and urine-like (not always). Very light blues somtimes look too much like the photo gallery for a newborn baby boy. (this can happen, also, with pink for a girl)
Sssoooo... long answer to a simple question... the best (imho) bright colors for a clean white page are lime green, yellow-orange, and soft magenta. But don't take my word for it... just look around. :-)
btw, an extra bonus of the lime-green and yellow-orange is that they look great on black, too!
