Colours
A layer’s colors picks 3 palette colours, in the order below. To recolour part of the background, change the palette colour in that position.
| Position | Paints | Default |
|---|---|---|
| 0 | Sky at the top | oklch(0.58 0.13 248) |
| 1 | Shaded side of the clouds | oklch(0.7 0.05 255) |
| 2 | Lit side of the clouds, and the sky near the horizon | oklch(0.99 0.01 85) |
Parameters
Every parameter is optional; one you leave out uses its default.
