Look up a colorLook up any hex code and get it in every color model: RGB, HSL, HSV and CMYK, with the text color that reads best on it. Says whether someone has named the color, and who, and for an unnamed color gives the nearest named one with its distance. Switch on the WCAG contrast check and the color blindness simulations to get everything in the one request.
Name a colorGet a name for any color: its own name if someone has named it, otherwise the nearest named color and how far off it is, as a distance and as a word from imperceptible to very different. One record either way, so a step that wants a word for a color never has to check which case it got.
Check WCAG contrastCheck a color's WCAG 2.1 contrast against a white and a black background: the ratio on each, whether it passes AA and AAA for small text, large text and UI components, which of the two it reads best on, and the text color OpenColors recommends for anything written on top of it. Built for checking a brand color before it goes on a page.
Simulate color blindnessSee how a color looks to people with each kind of color vision deficiency: protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind) and achromatopsia (complete color blindness). Each comes back as a hex code and RGB, ready to compare with the original or feed into another color action.
Search named colorsSearch the colors people have named on OpenColors by name, and narrow to one owner. Sort by name, owner, hex or when the color was named, in either direction, and choose how many to return, up to 50. Each result carries the hex, the name, the owner and the dedication.
Check color availabilityCheck which of up to 100 colors are still unnamed on OpenColors, in one request. Each color comes back as available or already named, with the name and owner when it is taken, and the two lists are summarised so a step can branch on the counts or take the available hexes straight into the next step.
Search brand colorsSearch the official color palettes of more than 600 companies by brand name, or leave the search empty and page through all of them. Each brand comes back with its colors in the order it publishes them, each as a hex code and a CSS-ready one, plus the brand's site and the design page the palette was taken from.
Get a brand's colorsGet one brand's official palette by name. The service only searches, so the name is searched for and matched here: an exact name or slug always wins, and failing that a partial name resolves when it lands on a single brand, so 'spotify' and 'the Spotify brand' both work. A name matching two brands is reported with both rather than guessed between.
Get color statisticsGet the state of the OpenColors catalogue: how many of the 16.7 million colors have been named, how many are still available, how many were named recently, the size of the partner programme, and who has named the most colors.
Check service statusCheck whether OpenColors is answering, how quickly, and what it reports about itself: its own status, the state of its database and its version. This is the one action that reports a problem as a value instead of failing the step, so a workflow can decide what to do about it.
