Petrichor palette
Sage Glade
Five petrichor stops with room to breathe — #00565d grounds, #00828c and #349ea8 do the talking, #5aabb3 softens, #77c8d0 lifts. The monochromatic bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
