I built a free color palette generator with accessibility checks — feedback welcome

I wanted a palette tool that goes beyond producing five random swatches, so I built Free Color Tool for designers, developers, and indie makers.

It supports complementary, analogous, triadic, tetradic, split-complementary, and monochromatic schemes. You can lock colors, check contrast, simulate color blindness, and export to CSS, SVG, JSON, SCSS, or Tailwind.

It is free and requires no signup. I would appreciate honest feedback from US-based designers and developers, especially on the accessibility workflow. You can test the tool here: free color palette generator
