What does ColorWell support?

Apple Silicon, Intel
JSON, Adobe .ase and Apple .clr palette files
Conversion between Hex, RGB, CMYK, HSB, HSL, and Lab color formats
Localized for English, German, Dutch, French and Korean

What does ColorWell's JSON file format look like?

The file should have the extension "json", and the structure should be a JSON dictionary, with only 2 entries:

paletteName - the name of your palette
colors - an array of hex color codes

Here's a basic example:


{
    "paletteName" : "My amazing palette",
    "colors" : [
        "#77e5ff",
        "#d577ff",
        "#ff9177",
        "#a1ff77",
        "#ff77e5",
        "#9177ff"
    ]
}

Have had this app for years. Years ago it was mildly useful. Now it is extremely useful. The full integration with system palettes makes it sing.

A great time and click saver. For pros, easily pays for itself in time value saved. For casual designers it makes color management more accessible. Color…

Latest Updated Review: Everything I asked for and more has been added to this app. If I could rate it more than five stars I would because it now does exactly what I want it to do.
