create_palette_link
Turn a colour palette you have chosen into a link that opens it in Coolours (coolours.perpetualsummer.ltd), where the user can preview the swatches, tweak them and export them. Use this whenever you propose a colour scheme, so the user can see it rather than read hex codes. Also returns WCAG contras
parse_palette_link
Read the colours and name back out of a Coolours link (coolours.perpetualsummer.ltd/create/...). Use this when the user pastes a Coolours URL, for example after editing a palette on the site, so you can apply their changes.
export_palette
Export a palette as CSS custom properties or a JavaScript object, with each colour named after its nearest named colour. Output matches Coolours' own Export feature. create_palette_link already returns the CSS; use this for the JS object, or for a palette you didn't create. Use the output as given:
