Duotone by default
Pick a shadow and a highlight once. Cards, nav and chips wash themselves in your ramp automatically.
Nimbus 2.0 — the duotone engine
Two colors. One loud page.
Nimbus stretches a single shadow-to-highlight ramp across every button, card and photo — so your product looks art-directed on day one.
Free during beta · No credit card required
Features
One ramp, everywhere
Backgrounds, buttons, badges and imagery all inherit the same bitone — consistency is the default, not a chore.
Fast like print
Pure CSS gradients and blend modes, zero image assets. Pages paint in milliseconds on any device.
Contrast, verified
Every background token ships with a validated text pair in dark and light mode, checked before publish.
How it works
Loud in three steps
Pick two tones
Set shadow and highlight in one token block. Ramps, washes and focus rings derive instantly.
Drop in content
Semantic sections snap to the grid — hero, features, pricing — with zero layout wrangling.
Ship in one file
Export a single self-contained page. Every hover, toggle and form reply stays in your palette.

FAQ
Straight answers
Do I need a designer on the team?
No. Nimbus ships art-directed by default: the ramp places color for you and every component is pre-tuned for both themes. Designers speed you up; they are never a blocker.
How do photos survive a two-color brand?
Every image is mapped through the ramp in pure CSS — grayscale, then blend modes for shadow and highlight. Any photo joins your palette with no pre-processing or asset pipeline.
Will visitors keep their theme choice?
Yes. Dark is the default, and each visitor’s toggle is remembered in localStorage, with a prefers-color-scheme fallback for first visits.
