A few fun pages to help you pick your colors for your website... The following plus a few more can be found on my website's Color Resources page.
Website Color Picker: "...will help you evaluate color combinations quickly and easily. It works equally well on MacOS or Windows. ...You can experiment with different colors for BGCOLOR, TEXT color, LINK color and VLINK color. ...click a color swatch in the appropriate section of the left window and see the color applied immediately to the chosen attribute in the right window."
Color Blender: Another visual color-code-producing site. This one lets you select 2 colors from color swatches, then blend the two in however many steps you specify. It's a Creative Commons share site, so you can copy the source code to have the Color Blender page handy on your own hard drive.
Color Schemer / Design in Harmony: My recent LVSOnline teacher says, "This is one of my favorites. You can use it on the web for free and you download any of the hundreds of color schemes posted there. The software available for purchase is really nice in terms of flexibility and power. It has a 15 day free trial."
