Check out the background for this page.  Do you notice anything?  That's right, the background color is constantly changing, fading from one to the next.  Notice how the background color never interferes with the color of the text.  Check out the code below:

// Change the background so that it is closer to the second random color. // If it becomes the second random color, create a new color. window.runBGFader = function() { var bg = runBGFader.start.combine(runBGFader.end, runBGFader.percent += 5); $("body").setCSS("background-color", bg); var fg = bg.getSafeColor(); $("body").setCSS("color", fg); if(runBGFader.percent > 100) { runBGFader.percent = 0; runBGFader.start = runBGFader.end; runBGFader.end = Color.random(); } setTimeout("runBGFader()", 100); } // Create the first two random colors and then start the fader. runBGFader.start = Color.random(); runBGFader.end = Color.random(); runBGFader.percent = 0; runBGFader();
