Palettes built around it
Wellness
Open in tool →Sage and terracotta feel natural and calm — the anti-hospital palette for wellbeing brands.
Crayon Box
Open in tool →Red, teal and yellow at crayon saturation — joyful, but on white with black type so it stays readable for grown-ups.
Clay & Linen
Open in tool →Terracotta, stone and olive on linen — the earth-tone default for ceramics, skincare and anything hand-made.
Desert Road
Open in tool →Sandstone and sand with a deep teal — the one cool note makes the warm colours look intentional rather than beige.
Kiln
Open in tool →Fired clay and ash on a dark umber — the earthy dark mode; warm enough that the dark surface reads as material, not void.
Darkroom
Open in tool →Sepia, faded ochre and a teal shadow on aged paper — the photograph-in-a-drawer palette, tuned so it still passes AA.
Mid-Century
Open in tool →Tangerine, teal and mustard on cream — the 1960s lounge trio, one of the few retro palettes with real hue contrast.
Graphite Mono
Open in tool →Five greys, no hue — the true monochrome; the accent is a lighter grey, so hierarchy comes from weight and size alone.
Oatmeal
Open in tool →Four warm greys from bark to oat — the neutral palette that photographs well and never argues with a product shot.
