hi! i was using PSP7 the other day and i found 2 colors that i really like and want to use for the theme of my website. the problem is i only know them by their values of red, blue and green. I need their hex code like #0099ff or something! i'm sure there's a way to do it but I can't figure it out! please help me!

if you know their values of RGB, then type them into your Color Palette, in PSP. Then select the "Add to custom".....which will save the selection for future use.

I know that. I already have done that but what i need to know is their code because wen u make ur site u have to use that code to specify colors for scrollbars, bgs, text, etc. I want to know how to find that.

This may help...
