When reporting a problem, it helps enormously if you can include your device, your iOS or iPadOS version, the app version (shown in the About sheet), and what you were doing when it happened. A screenshot of the palette, or the exported code, is always welcome.

Common questions
Because lightness in OKLCH matches what your eye actually perceives. Generating a palette in it means a red and a yellow at the same lightness read as equally heavy, which is what makes a set of tokens feel like one system. Colours that fall outside the display gamut are mapped by reducing chroma, so the hue you chose is preserved.
They are WCAG 2.1 ratios. AAA is 7:1 or better, AA is 4.5:1, and AA Large is 3:1, which applies to text at roughly 18pt and above or 14pt bold. Anything below that is marked Fail. The exact ratio is shown beside every grade so you can see how much headroom you have.
The report tells you which of two things went wrong. If the deficiency caused it, the colours differ mainly in hue, so change one in lightness instead. If they were always too close, no simulation was needed to break them, and they need separating regardless.
In your own iCloud account, synced privately across the devices you are signed in to. We have no server and no account, so we never see them. If presets are not appearing on a second device, check that iCloud Drive is on for both.
The export uses the token names shown in the palette, so they stay consistent across CSS, SwiftUI and Android XML. CSS can be written in OKLCH or HSL, and light and dark can be exported together as one theme. If you need a format we don't cover yet, tell us, as that is usually how a new one gets added.
It ships in English, German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese and Simplified Chinese, following your device language. Generated code comments stay in English deliberately, since exported code usually ends up in a shared repository.
Privacy and terms
Policies
Read the UI Color Palette Designer privacy policy for exactly what the app does and doesn't collect, and our app terms of use for the terms covering this app and our others.
What we don't do
There is no account, no login and no server of ours. Nothing you make in the app is uploaded to us, and there is no tracking or analytics of any kind. Your presets and settings stay on your devices and in your own iCloud.
Still stuck?
Feature requests are genuinely welcome too. The contrast report and the colour vision simulator both exist because people asked for a way to check a palette before shipping it.
