September Colors: 3 Ready-to-Use Palettes
September can suggest the first warmth of autumn, the month’s sapphire birthstone or the softer colors left at the end of summer. These three original palettes turn those interpretations into practical HEX codes.
Palette 1
Early Autumn
Golden, terracotta and olive tones mark the seasonal transition, balanced by slate blue and a soft cream for backgrounds.
Palette 2
September Sapphire
A blue-led palette inspired by September’s sapphire birthstone, moving from saturated blue to pale periwinkle and deep navy.
Palette 3
Late Summer
Dusty pink, warm cream, muted green and faded blue create a restrained palette for weddings, stationery and editorial layouts.
