Blue Hour palette
Malty Crater
Five stops tuned to sit together without fighting — #007085 ink anchors the set, #85e5ff opens it up, and #009dba, #3cbad7, #67c7e1 cross the middle in a complementary arrangement. Malty Crater suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
