Pastel palette
Seafoam Foundry
Five pastel stops with room to breathe — #395e9c grounds, #6288c6 and #7da4e4 do the talking, #92b4eb softens, #b4d1ff lifts. The tetradic 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.
