Radial Gradient as a texture I'm trying to make a radial gradient to put a sunburst on this guitar body similar to this:

What I have so far is this node set up:

EDIT

So.....according to this reasoning if I set this up like this I should be able to get a blend between black pink and white in a radial pattern which still isn't even close to happening......any other thoughts
Worse still is I did find a clear shot of a sunburst guitar to do a UV projection but its the back and so the s curves are completly ragged and thats not going to get it.......sorry, had to use the answer section because the comments don't seem to have a way to post a picture.
You'll have to give the color ramp something to work on through its "fac" input (using e.g. the "fac" output from your gradient node).

But your example does not have a simple radial gradient, but one that follows the body curve. In that case, it might be easier to make an image with the gradient you want and use UV mapping on the sound board to place the color.
