Tool:Accessible color palettes for charts and dataviz

Question

[Pierre]

Hello,

I have created a tool that generates color palettes for data visualization and charts. While many existing tools create colorblind friendly palettes, mine also ensures the colors remain distinguishable in grey scale printing (for academic papers and publications).

The project is open source and you can contribute to it if you want to improve it or correct potential errors.

That's a really nice touch for colorblind folks !

Some enhancements that would help for publications :

• Select a number of color (>5)
• Possibility to lock a color, that would stay lock after regeneration
• Complementary colors
• Cold and warm palettes
• Select shades
