Monochrome palette
Mercurial Gallery
Five stops tuned to sit together without fighting — #004577 ink anchors the set, #6eb5f7 opens it up, and #006db6, #2f89d4, #5298d9 cross the middle in a tetradic arrangement. Mercurial Gallery suits indie game interfaces with a strong day-night rhythm. The darkest and lightest stops clear AA as a text pair.
