Rainbow — Pro

The free add-on does everything the old one did. Pro adds the one thing its users kept asking for and never got.

Free, forever	Pro
Gradient across the selection Alternating colours All six palettes Saved setups — name a combination, reuse it in any document Letters grow / shrink Upside down text Remove colours Put it back (undo)	Your own colours — any hex values, as many as you like

Why this is the line. A 2-star review of the add-on we are replacing says it plainly: “I was expecting it to have custom randomized font colors… the random colors wouldn't be that bad if they weren't atrocious… there's no real custom colorization feature.” The palettes had to be good, and they are free. Choosing your own is the part nobody shipped.

Price

If your licence lapses

Nothing is taken away from your documents. The colours you have already applied stay exactly as they are. Rainbow simply goes back to the free palettes.
