colorLab is a JavaScript library to calculate the difference between two colors in DeltaE (CIEDE2000).
npm install colorlab
import colorlab from colorlab;
let color1 = new colorlab.CIELAB(50.0000, 2.6772, -79.7751);
let color2 = new colorlab.CIELAB(50.0000, 0.0000, -82.7485);
// CIEDE2000 tells you the DeltaE, or perceptible color
// difference, between CIELAB color1 and CIELAB color2
color1.CIEDE2000(color2); // → 2.0425
// or
colorlab.CIEDE2000(color1, color2); // → 2.0425
npm test
- Lint the library and tests, then run the unit testsnpm run lint
- Lint the source and unit testsnpm run watch
- Continuously run the unit tests as you make changes to the source and test files themselvesnpm run test-browser
- Build the library for use with the browser spec runner. Changes to the source will cause the runner to automatically refresh.npm run build
- Lint then build the librarynpm run coverage
- Generate a coverage report
The browser spec runner can be opened in a browser to run your tests. For it to work, you must first run npm run test-browser
. This will set up a watch task that will automatically refresh the tests when your scripts, or the tests, change. The spec runner file is located at test/runner.html
: open it in your browser to run tests.
