A colour is written as its design token (`<span style="color: var(--mmo-color-bad)">`), never as a hex
value: the text follows the theme -- a reskin, the dark mode -- like the rest of the page does. So the
list is of token names, and a colour pasted from elsewhere is dropped (`MMO.editor.ALLOWED_STYLES`).
//another palette for every editor of the page
MMO.editor.Tool.Shared('color').colors = ['brand', 'bad', 'ok'];
