Umber Outpost
Five stops tuned to sit together without fighting — #006b86 ink anchors the set, #88dfff opens it up, and #0098bd, #3ab4da, #65c3e3 cross the middle in a triadic arrangement. Umber Outpost suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
