Nebula palette
Opal Ridge
Five nebula stops with room to breathe — #004b4b grounds, #007776 and #319291 do the talking, #549f9e softens, #71bcba lifts. The tetradic bones keep it coherent across outdoor gear branding that reads in sun and shade. The darkest and lightest stops clear AA as a text pair.
