Make Rainbow Art on Procreate!

What can we use instead of the Procreate app or an iPad if we can't find them?

If you don't have the Procreate app or an iPad, use a similar drawing app (like Autodesk SketchBook or Adobe Fresco) and create a new canvas sized to your device while following the same steps with a sketch layer, brush library, and layers for 'Base Colors'.

My colors don't look like they're glowing after duplication or my paint keeps going outside the sketch lines—what should I try?

If the duplicated 'Base Colors' layer doesn't glow, make sure you changed its blend mode to Overlay or Add and increase its opacity, and to stop paint bleeding outside your sketch lines lower the brush opacity or use a selection/alpha lock before painting solid color bands.

How can I adapt this project for younger children or make it more challenging for older kids?

For younger children simplify the 'Sketch' step to a few large arcs and let them fill them with the soft round brush on the 'Base Colors' layer, while older kids can duplicate layers, experiment with Overlay/Add blend modes, use the Smudge tool for subtle blends, and add textured brush details.

What are some fun ways to extend or personalize my rainbow artwork?

To personalize your piece add a new layer to hand-letter a name or tiny scene above the texture layer, try custom brushes for unique textures, tweak the duplicated layer's blend mode for different glow effects, or use Procreate's Animation Assist to make the rainbow shimmer before sharing on DIY.org.
