Delrino: Try this... Make a new layer and use the ellipse marquee tool to make a circle with an arc large enough for your rainbow. Use the gradient tool in KPT to set up your colors and set to circular fill. Once you have the circle filed with the gradient, use the eraser to get rid of the parts you don't need. If you use the airbrush tool with the eraser, you can set spacing at about 50% and opacity down to about 5% to nibble away at the ends of your rainbow so it "fades" into the ground and sky (double click on the brush to bring up the dialog box for the brush). Now adjust the layer transparency until it looks "right" to you. You may have to tone down the saturation a bit, but be carefull or you'll get banding between the colors. 'Hope this works out for you... - Jim
