Kay's Marvel Rivals Rainbow Text Gen

A mid september '25 Rivals update introduced the ability to change text colors in the rivals game chat. This is a quick n' dirty tool I threw together quick to rainbowify text.

This works by prefixing the letters / words with a hashtag, then one of the color codes, ex '#R' to make everything after it red.

However, each one of these also counts as text within the window, so rainbow-ified text is usually only about 1/3rd of the total text limit (100 characters, usually ~33 rainbowified, skipping spaces)

Select a mode below (letter does a color change per letter, word does color change per word) and hit copy to copy it to your clipboard. Then just open the chat window and press CTRL+V to paste it in.

Also if you see kaytheborb in-game, say hi! :3
