Color combinations in hex (Two-tone, Tri-tone, Quad-tone palettes)

The data scraped from 80 Eye-Catching Color Combinations For 2021!.

I don't own anything on this data.

copy($$("h3")
     .map(v => v.textContent)
     .map(text => ({text, colors: [...text.matchAll(/#[0-9A-F]{6}/g)].map(m => m[0])}))
     .filter(v => v.colors.length))
