App UI colours from an image

An interface needs one colour in many strengths: a pale tint for backgrounds, a mid tone for buttons and a deep one for pressed states. Drop an image and each colour comes with a full scale. Nothing is uploaded: your image stays in your browser.

How it works

  1. Add an image

    Drop a picture on the page, paste it with Ctrl+V, or browse for a file. A logo, a photo, a screenshot or a product shot all work.

  2. Choose how many colours

    Pick 4, 6, 8 or 10. The most common colours come first, with the share of the image each one covers, so you can see which colour leads.

  3. Pick, scale and copy

    Click the image to pick any exact pixel with a magnifier, open an eleven-step tonal scale for any colour, and show the colours as HEX, RGB, HSL or OKLCH.

  4. Export it

    Copy the palette as CSS variables, a Tailwind theme, SCSS, JSON or plain text, download it as a file, or save a PNG strip of the colours.

Questions about a app UI colours

How do I get a app UI colours from an image?

Add your image, and 8 colours are chosen for you. You can change that to 4, 6, 8 or 10. Then open Export, choose JSON with tonal scales and copy the code. Use the 100 and 200 steps for hover backgrounds, the 600 step for buttons and the 900 step for text on light surfaces.

Will the scale steps pass accessibility checks?

Not automatically. Steps are spaced by lightness, so dark steps usually work with white text and light steps with black text, but run any pair through the contrast checker to be sure.

How many colours should a app UI colours have?

Eight base colours plus their scales cover most apps. Choose one as primary, one for success and one for warnings, then keep the rest as neutrals.

Is the image I use for my app UI colours uploaded?

No. The picture is read by your own browser in a background worker, so your app UI colours stays private and the page keeps working offline once it has loaded.

Check that these colours are readable

A palette looks fine until text sits on it. Test any pair from your palette against WCAG AA and AAA, and get the closest passing colour when one fails.
