How do I connect ColorUI to Lodol?

Authenticate ColorUI once from your workspace and every action and trigger it supports becomes available to drop into a workflow. There is no glue code to write or maintain.

ColorUI

Images & DesignUtilities

Color tools from ColorUI's free public API: convert any CSS color into HEX, RGB, HSL, LCH, OKLCH and LAB at once, check the WCAG 2.1 contrast ratio between a text color and a background with AA and AAA pass or fail flags, and generate palettes from a few words about a brand or a mood, from a harmony rule around a base color, or at random. Every palette comes back as hex codes with a link to it on colorui.io, so a workflow can turn a brief into swatches, check a color pair before it ships, or convert a designer's OKLCH into the RGB a legacy tool needs. No account or API key required.

Steps your workflow can run in ColorUI.

Convert a colorConvert any CSS color into HEX, RGB, HSL, LCH, OKLCH and LAB, all at once or one at a time, each with its components and a CSS string ready to paste. The step that turns a designer's oklch() into the rgb() a legacy tool needs, or a named color into its hex for a template. No API key required.

Check contrastCompute the WCAG 2.1 contrast ratio between a text color and a background, with pass or fail flags for AA and AAA at normal and large text sizes and for graphics. The step to run before a color pair ships, with one boolean to branch on. No API key required.

Generate a palette from a promptGenerate a palette from a few words about what it is for, such as a brand, a product or a mood. Comes back as hex codes with the intent the service read into the prompt, an explanation for each color, and a link to the palette on colorui.io. Set a variant to make the result repeatable. No API key required.

Generate a harmony paletteBuild a palette around one color by a color-wheel rule: complementary, analogous, triadic, tetradic, split-complementary, square or monochromatic. The step that turns a brand color into a set of accents that sit well with it, as hex codes with a link to the palette. No API key required.

Generate a random paletteDraw a palette of two to eight colors at random, as hex codes with a link to the palette on colorui.io. The step for a fresh scheme every run: a color of the day, a placeholder theme, or inspiration to pass on to a designer. No API key required.

Check service statusCheck whether ColorUI is answering, how quickly, and how much of the rate limit is left this minute. This is the one action that reports a problem as a value instead of failing the step, so a workflow can branch on it, pace itself, or fall back to a saved palette when the service is down. Being throttled is reported separately from being down. No API key required.
