Colour pairings & usage tips

Use these colours.

Use the darkest swatch as the night-time setting, orange for the focal shape and purple for a secondary detail. Leave clear space around headings and controls.

Text & contrast.

Orange can support dark lettering better than white lettering. Check purple-on-dark details separately and keep thin decorative strokes away from essential information.
