The tile backgrounds on the following pages feature semi-transparency, so they will work over many different background colors. Certain tiles will look better over darker backgrounds, others will work best with light backgrounds, and some will work with any tone.
Why are OverAlls useful? If you lay out your pages with a style sheet and use OverAll backgrounds as decorations on your pages, all you have to do to change the palette for your entire site is to change your background colors on the style sheet, and the whole site has a new look. Or maybe you want different colors for different categories of pages, but would like to use the same decorations. Or perhaps you want to change your colors every day, or give your readers their choice of colors. OverAlls work great for all these purposes. (Plus, they're just plain fun!)
