Build cohesive and accessible color schemes : schemist.fglt.fr
Note that Schemist is still in its early days, so things might be subject to change. Feel free to report bugs or suggest improvements!
Schemist builds on color theory to let you create cohesive color schemes with ease. Colors are defined as a tree, where each one depends on its parent. This allows for building a whole palette based on one color, and get a whole new palette by just changing this base color.
Schemist provides modifiers, for example to lighten or darken a color, shift its hue, find common harmonies (complementary, triad, tetrad, ...), find contrasting colors, and more.
To ease the process, a set of presets is included, allowing you to generate whole palettes from a base color in one click.
While building your palette, you'll be able to review the contrast of each color combination to ensure that they are accessible to everyone.
The whole thing is reactive, so play around!
Dear color theory experts, please don't get mad.
Schemist uses its own "color space", or more prcisely mixes and matches two of them. It rotates hues with Oklch, which has more uniform hues than, say, HSL. However, instead of using Oklch's chroma and lightness, it uses saturation and lightness from Okhsl, as it is a more human-friendly way of interacting with color.
Yes, it is probably wrong on many levels, but to me it yielded the best results overall, in terms of ergonomics and outputs.
Schemist is build upon these fabulous projects and resources:
- SvelteKit
- Culori for the core color mechanics
- color-name-list to name colors
- nearest-color to find matching color names
- APCA to calculate contrast ratios
- Inter for the main font
- Source code pro for monospace texts
- Font Squirrel generator to subset Source code pro
