Prism colours the text you select — rainbow, a gradient that blends across a whole sentence, random
colours, growing letters, or the whole thing flipped upside down. It works in Google Docs™ and in
Google Slides™.

FREE, FOREVER
• Seven palettes: rainbow, sunset, ocean, forest, candy, fire, greys
• Gradient — blends across the whole selection, even across several paragraphs
• Random colours, reshuffleable, always drawn from the palette you chose
• Colour each letter, each word or each line
• Growing letters — a smooth size ramp from one point size to another
• Flip text upside down — “Hello” becomes “olləH”; Ctrl+Z puts it back
• Works in presentations too, including text inside tables and grouped shapes

EXACTLY THE COLOURS YOU PICK
This corner of the store has one recurring complaint: the tool quietly changes 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 code you selected. A gradient starts on your first
colour and ends on your last one, not near them. Spaces are skipped rather than coloured, so the rainbow
keeps its rhythm instead of drifting.

PRISM PRO — YOUR OWN COLOURS
Paste your brand's hex codes and every effect uses them instead of the built-in palettes: the gradient
blends between them, the random mode picks from them, the rainbow cycles through them.
$29 a year or $69 once, covering every add-on in the suite.
