Just bought a lifetime license for Atmos because it is just sooo good for creating perceptually uniform color palettes – including a shade generator, a contrast checker, OKLCH support, CSS export, a Figma plugin, online sharing, and, and… 😍 👉 atmos.style (No affiliation, just genuine excitement! 😁)

My new favorite is atmos.style, which works exactly as I expect, with access to OKLCH color space, P3 color gamut, and visual controls with curves and all the stuff you'd need to create something nice! 💖

I like working in @atmos_style. Adding all of the variables and quickly selecting a swatch to key off of for contrast is fast.

Color Generator FAQ

A color generator is a tool that automatically creates color combinations based on color theory rules and your input. Instead of picking colors manually, a generator finds harmonious options that work well together. Atmos generates both brand colors and semantic status colors (like success, warning, danger, and info) so you get a complete palette ready for UI design, not just a few nice shades.

Semantic colors are colors assigned to specific meanings in a user interface. The most common are success (green), warning (yellow or orange), danger (red), and info (blue). Rather than choosing these arbitrarily, Atmos derives them from your primary brand color so they stay harmonious with the rest of your palette. Using semantic colors consistently helps users understand status messages and feedback at a glance.

Brand colors represent your product identity, your primary color, secondary accent, and any supporting palette hues. Semantic colors communicate meaning and status in your UI, such as error states, success messages, or informational alerts. Both sets need to feel cohesive. Atmos generates semantic colors derived from your brand color so the two sets always complement each other.

Start with the mood and values you want your product to convey. Blues suggest trust and reliability, common in fintech and productivity tools. Greens communicate health and growth. Oranges and yellows feel energetic and approachable. Once you have a direction, use Atmos to explore colors within that range, filter by meaning and style, and generate a full palette from your chosen primary color.

A typical UI palette needs a primary brand color, one or two accent colors, a set of neutral grays for backgrounds and text, and four semantic colors (success, warning, danger, info). Each of those colors should also have a range of shades (usually 9 to 11 steps from light to dark) for use across different UI contexts. Atmos generates all of these from your starting color so you have a complete, consistent system.
