Inspired by some other pixel patterns posted here, realized these could be useful.
These stars are in greyscale by default. You can use a gradient layer or a clipped layer on them to recolor them, or you can just "rasterize" the layer & recolor. One set is at 300px (x3), one is at regular (100px) size. Use whichever suits your drawing more!
Big 300px:


Small 100px:
