The createScale() function is basically a wrapper function for creating a d3 linear scale for colors, with a few enhancements that aid in the generateContrastColors() function. Although functionality is comparable to Chroma.js, the choice of D3 color is based on the additional modules available for state-of-the-art color appearance models, such as CIE CAM02.

This project is currently built using D3 color. Since the WCAG requirement is defined as a minimum contrast requirement, it should be fine to generate colors that are a little more accessible than the minimum. This is exaggerated by the various colorspace interpolations. If 8.58 is input as the target ratio with the starting color of blue, the output will not be exact. If we change any one value in the RGB channel for either color, the ratio changes: This has to do with the available colors in the RGB color space, and the math associated with calculating these ratios.įor example let's look at blue and white. You may notice the tool takes an input (target ratio) but most often outputs a contrast ratio slightly higher. Why are not all contrast ratios available?

Sometimes it's easier to express what you can do by showing you. The URL updates with your parameters for easily sharing links to team mates, and the app displays the specific config parameters when designers send you a version that they approve. The tool exposes an interface to generateContrastColors() function and displays visual aids for modifying the selection of a variable color and the target contrast ratios (swatches) to produce. The Leonardo web application is a tool for designers and engineers to collaboratively build color scales for use in user interfaces.
