How to color Mermaid at an Underwater Castle (with suggested palette)
Colors that work well together — tap any swatch to copy its hex.
Color the castle first, walls then roofs then flags, since it sits furthest back in the scene. Do the seaweed and seabed next, and finish with the mermaid herself, tail before hair. Tap any color below to copy its HEX code.
Additional Coloring Tips
1Tower roofs
Give all three roofs the same red so the castle reads as one building, not three separate towers.
2Arched windows
Fill each window deep blue so the openings look like dark rooms rather than painted panels.
3Tail scales
Lay violet across the whole tail, then darken the lower edge of each scale row with a sharp pencil.
