Heather Oasis
Five stops tuned to sit together without fighting — #00658d ink anchors the set, #93d8ff opens it up, and #3390be, #52acdc, #72bbe4 cross the middle in a tetradic arrangement. Heather Oasis suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
