I'm customizing a color picker's default showing colors which will be used as background colors. I'm wondering if there is a collection of the colors that are particularly useful in practical web design. Like nobody(hopefully) would use #f00 as a 100%-width page's background color while #fff is a universally usable one, there's DO'S and DONT's when it comes to picking background colors. So what are the candidates in your opinion?
I know this could be subjective, but generally I believe there IS a solid set of them.
[edit] : I kinda have an idea to customize the color picker in a logic way, first pick a buch of hues, them for each hue, start from the possible lightest of saturation to the possible heaviest. A bit demenstration:
gray [ #eee, #ccc, #ddd, .... ]
green [ ... .... ... .... ]
blue ....
yellow
brown [
