Sometimes it can be quite nice to be able to display a color spectrum (ie a rainbow effect) maybe to color a background or as a fancy border round a control . It's quite difficult to smoothly transition through the different colors of the spectrum using the RGB system. It's much easier if you use the HSV color system. I've produced a conversion utility to convert from HSV to RGB and used it to display a scrolling spectrum as a demo. Feel free to rip out the conversion code and use it.  1196326839_438_FT0_rainbow.zip | ||
