Prism

Rainbow text, gradients, random colours, growing letters and upside-down text — inside Google Docs™ and Google Slides™. Exactly the colours you pick.

Free forever: every effect, in both apps — seven palettes, blend a gradient across a sentence, colour each letter, word or line, grow the letters, flip the text. That is everything the old text add-ons did, plus the slides support they never had.

Exactly the colours you pick

The add-ons in this corner have a long-standing complaint: they quietly change the colours you chose — “it defaults to a lighter version of the colors I choose”, “the selected colors are ignored, and it just uses some different shade”. Prism writes the exact hex code you selected. A gradient starts on your first colour and ends on your last one, not near them.

What it does

Palettes — rainbow, sunset, ocean, forest, candy, fire, greys.
Gradient — blend across the whole selection, even across paragraphs.
Random — from your palette, not from “atrocious” defaults, and reshuffleable.
Per letter, per word or per line — spaces never eat a step of the palette.
Growing letters — a smooth size ramp from one point size to another.
Upside down — ‘Hello' becomes ‘olləH'. Ctrl+Z puts it back.
Works in slides too, including text in tables and grouped shapes.

Prism Pro

Your own colours. Paste your brand's hex codes and every effect uses them instead of the built-in palettes. See Prism Pro →
