I got carried away with colors and now the whole piece looks ruined

FIX IT NOW

1. Adjustments → Hue, Saturation, Brightness → drag Saturation to zero. You're now looking at grayscale. Do the values make sense — can you see distinct lights and darks? If yes: it's a color problem, not a structural one. Completely fixable
2. Drag Saturation back to where it was, then reduce it by 20–30%. Oversaturation is the single most common reason digital art looks garish or cheap
3. Move the Hue slider slowly — 5 degrees left, then 5 degrees right. Sometimes a small shift unifies a broken palette instantly
4. If specific colors are wrong but the rest is fine: use the Automatic Selection tool to select just that color area → Adjustments → Hue/Saturation/Brightness on the selection only
