How Do i add colour to this image texture? I think i have bumped it correctly? I now want to add colour so that the planet looks nice. Also I am having trouble with the image texture after unwrapping and scaling in the uv image editor- not sure how to fix this? As shown in pics. Thanks.

I have attatched a detail of the updated nodes, although I cant see the colour option the same as shown in your multiply nodes.
i think you can do it like in this example. your uv maps must be wrong unwrapped tho.
