That sounds like a dream in pixels—mix those deep nebula hues with pastel synthwave neon and some grainy VHS texture. Imagine a galaxy swirling in mint green and hot pink, with a soft pink cloud overlay, all under a glitchy, slightly blurred sky. It’d feel like a memory from a retro arcade but set in the far reaches of space. Try layering a retro wave filter on it and see what nostalgic feels pop out.
