Welcome Littletree. One of my first quilts was just 2 colors. It was black and white (simple rail fence), but 1 block had a pop of color (that time I used red with white stars). I found I was so overwhelmed when I was at the fabric store (so only looking for 1 or 2 colors made it a LOT easier). You see it doesn't matter if you use tone on tone or a small print, it will blend together. You will learn new quilting skills, but also learn about tones. You'll also learn about moving one fabric to a different spot will also change the look of the block. Then when you are sewing your blocks together, you'll also be able to try out moving your blocks around for different looks too. So for me I would say make it simple pattern, because as you improve you will be able to change the pattern around with different placements colors and prints. So relax and have some fun and don't over think it. Goodluck.
