So glad to hear that you want to try this wonderful craft.
I'm enerting the way-back machine to when I first started. I knew a about color (art major), nothing about quilting.
It might be helpful to you if you try to use a two color quilt to start with. Do a search for patterns and see what you can find. I think I made an Irish Chain. Another idea would be to use one of the great kits available to start with until you get comfortable with color. Taking a class can also help with color comfort. But remember, It is your quilt, others can only guide you.
peace :D
