Check out these two photos. Same blocks. Same layout. Different color placement. What do you notice? What pops out, and what doesn't? What does your eye see? (Or rather, notice what contrast attracts your eye.)
Here I've tried to place them side by side so you can compare the two. Neither is RIGHT or WRONG, they are DIFFERENT, and show you how color (and value placement) can change the whole thing. Which one you might use depends entirely on what you want to emphasize.
Since the design with the colored diamonds (2) remind me of Treasure Trove, I probably won't make that one. But I am not quite sure I want the blue diamonds in (1) to be so wimpy and disappear.
I think I'll try to make some other lighter triangle blocks and use them also, and just keep the darker colors for the triangles that complete the star pattern, because it would be a nice thing to have two ideas working together. Here the dark shapes that make the star tend to pop forward. That's fine with me, but it would be fun to get another set of lighter colors to sink backward (like the light blue) to make that "layer" more interesting than just being one color. It'll be a fine balancing act and until I actually put blocks on the design wall, I'm not sure it will "work" the way I want it too.
It's going to be fun to find out.
