Nebula is a vivid analogous color palette tagged space, dark, cold. Analogous neighbors on the wheel (Indigo, Amethyst, Cotton Candy) give it a natural, low-tension flow. Saturation runs high, so use the brightest color sparingly and let the others carry the surface area. Warm and cool hues are mixed, which adds depth.
