Palettes built around it
Ink & Paper
Open in tool →Two greys and one ink-blue link color: the palette of a well-set book page.
Console Light
Open in tool →A sober docs palette: one blue for interactive, one green for success, zinc greys for everything else.
Graphite
Open in tool →A greyscale system with a single amber — the accent does all the work, so allow one per screen.
Launch Orange
Open in tool →Orange is the rarest SaaS primary, which is exactly why it stands out on a pricing page; cyan keeps it from feeling like a hardware store.
Fresh Juice
Open in tool →Orange, mango and mint — a sugar rush; keep the type black so it stays legible under all that color.
Learning App
Open in tool →Green, blue and orange at full saturation: the gamified-learning look, where every color is a reward.
Playground
Open in tool →Orange, blue and green — the colors of playground equipment; loud, cheerful, obviously for kids.
Studio Grey
Open in tool →A pure greyscale with a single electric blue — the portfolio palette that makes work look considered.
Diner
Open in tool →Cherry red, mint-teal and butter yellow — chrome-and-vinyl retro; the red does the work, the teal cools it.
Fireside
Open in tool →Cranberry, pine and brass on a charcoal night — the holiday palette without the clichés, because the surface is cold.
Stone
Open in tool →Stone greys with a faint warmth — Tailwind's stone scale used as a whole palette: interfaces that want to disappear.
