Monochrome palette
Cornsilk Glade
Five monochrome stops with room to breathe — #5f5d00 grounds, #898700 and #a4a333 do the talking, #b2b25a softens, #cfcf77 lifts. The split-complementary 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.
