I painted my boys' bedroom Blue Twilight - https://www.lowes.com/pd/Valspar-8-o...Sample/3811945 Their room doesn't have a lot of natural light, so the color leans toward a grey-ish blue. Not sure how much natural light would affect that, but I really like how it turned out for us.

It's not specifically a space room, but one wall has glow in the dark stars and a Moon in My Room hanging, and it seems to work really nicely with that paint color. It's also a shade of blue that doesn't seem like it will feel babyish in a few years (my oldest is now 13 in that room and still likes it), and as their interests have changed, it's a color that works pretty nicely with whatever they want to hang on their walls.
