The URL: the palette hash, ?site= and ?scripts=0

The hash is the palette, left to right: #264653-2a9d8f-e9c46a-f4a261-e76f51. Each color is a hex code without its #, 3 or 6 digits, and there are 2 to 10 of them. Recolor writes them in lowercase with 6 digits, and reads the short form too: #fff-000-c33 becomes #ffffff, #000000, #cc3333. A hash it cannot read, such as one with a single color or a 4-digit code, is replaced by the palette on screen.

The address follows the palette as you work: Recolor rewrites the hash a moment after each change without adding a browser history entry, so Back still leaves the page. Undo and redo are Recolor's own, 100 steps deep. Editing the hash in the address bar loads that palette as one undo step.

A Coolors palette link carries the same hex codes the same way after the domain. Swap the domain and the palette opens in Recolor:

https://coolors.co/264653-2a9d8f-e9c46a-f4a261-e76f51
https://recolor.page/#264653-2a9d8f-e9c46a-f4a261-e76f51

Recolor reads the last run of hyphen-joined hex codes in whatever follows the #, so pasting a whole Coolors address after recolor.page/# works as well. That covers both forms Coolors uses: coolors.co/<codes> opens its generator, and coolors.co/palette/<codes> its page about a palette. A Coolors link with more than 10 colors does not exist, since Coolors stops at 10 too (5 on its free plan, as its pricing page said on October 8, 2026). What Coolors offers beyond the palette itself is on the Coolors alternative page. The other way, the Export panel's Coolors tab gives the Coolors link for the palette on screen; Export formats shows every format, and turning a Coolors palette into code walks through a full round trip.

?site= holds the address of a page to load when the link opens; ?scripts=0 loads it with its scripts off. Recolor writes both into its own address as you load pages, so a reload brings back the same page, and the Export panel's Link tab builds the whole link for you:

https://recolor.page/?site=https%3A%2F%2Fstripe.com%2F&scripts=0#264653-2a9d8f-e9c46a-f4a261-e76f51

The page address is percent-encoded by the browser, which is why https:// appears as https%3A%2F%2F; typing it unencoded works too. A sample or an uploaded file cannot be put in a link, since Recolor keeps no copy of a file: a link made then carries the palette alone. How each source loads is on Loading a page.

Locks, overrides from Site colours, the Strength and Neutral tint sliders, and saved palettes are not in the URL. Locks and settings belong to the tab you work in; overrides belong to the page on screen and its analysis; saved palettes stay in the browser, up to 50. Whoever opens your link gets the palette and the page, with the default mapping of Strength, neutral tint and overrides.
