I normally stay away from using hex codes for color and instead tile a tiny slice of the actual color anywhere I can. Its a bit more coding, but it makes the color what I want without too much issue even on dialup.
And a websafe color can only effect how the color is viewed which is the easiest part of a design. Your design may look right, but if its still scrambled who cares?
