360° feed: the Dune palette on a sample weather app screen, with its name, mood and a contrast score of 8 out of 8 passing.

A working prototype. Pro features unlock with a simulated purchase, so no payment is ever taken.
One palette in every context: buttons and form controls, text on each background with its contrast score, and a 50 to 950 colour scale.
Accessibility in the preview: a chart warning that two colours can’t be told apart with achromatopsia, the vision simulation menu, and swatches with their contrast ratios.
The Signal palette in detail, with each colour’s HEX, RGB, HSL and OKLCH codes, and the same palette on the feed in dark appearance.

360° is a colour app for UI designers, designed as a companion to the font app 72pt: Fonts for Designers. Where 72pt shows your own words in a typeface, 360° shows a palette on a real app screen before you commit to it. Swipe through 24 palettes, and scroll the side rail to see each one as six app screens, components, text, a chart, swatches and a 50–950 scale.

Accessibility is part of the preview, not a separate report. Eight contrast checks run on every palette in light and dark, failures show on the exact element with a one-tap fix, and a vision lens simulates four kinds of colour blindness. A colour app has to pass its own checks, so 360° keeps 72pt’s look but fixes seven of its colours that fell short of WCAG contrast. Palettes export to Xcode colour sets, Figma variables, CSS, Tailwind and SwiftUI. It’s a web prototype styled as an iOS 26 app: full screen on an iPhone, inside a phone frame on a laptop.
