Here are some of my most-used resources for colour palettes

Lists of colour palettes (made by humans)

• My favourite site for this: https://www.colourlovers.com/palettes/most-loved/all-time/meta (advanced users: see also the JS package: nice-color-palettes)
  • Grab colour-lover palettes to clipboard as an immediately useful javascript array of hex-codes: https://nice-colours-quicker.netlify.app/ (src)
• KGolid's Chromotome: https://kgolid.github.io/chromotome-site/ **
  • and my modification here (temporary) which allows you to click a palette to copy it directly into clipboard.
