iWantHue – a web-based color palette generator that offers powerful options for choosing colors that perfectly match each other.
It works by specifying a range of color, luminosity and other things. Putting all the necessary settings, you can get a palette of any size.
The palette of colors is available in several formats (RGB or HEX, as well as a list or JSON). Here, too, there are presets for rapid creation.
iWantHue – is an open source project, which means that anyone can use this tool to create palettes using only javascript.
