"colorier", which is currently used, is a verb and proposed "couleur" is
a noun: the block in question does not change colour of anything, it
creates new colour instead, thus noun is more applicable.
Also, noun is used in French translation of "random colour" block:
"couleur aléatoire".
This will be used to define constants accessible in JSON block definitions. Messages with descriptions that include `{{Notranslate}}` will not be included in the translation files sent to TranslateWiki. Instead, they are written to `msg/json/constants.json`, and later merged back into the `.js` files, similar to synonyms.
