I would like to make an image that should take place in heaven. Part of the image has a circular rainbow. I want the rainbow to look realistic and don't know how to approach it. I've made a flat torus, and it looks really bad. Any suggestions?

Never mind. I decided to cheat and make a rectangle, and texture it making a gradient rainbow in photoshop, then making a gradient circle for the alpha. Applying the rainbow colors to the color texture, and the black/alpha gradient image to the transparency texture at 100% achieved the desired results. I was originally hoping to model a rainbow or something that would do the same job. I am still open to options and ideas if you have any. Thanks.
