As a designer, your clipboard is constantly filled with hex codes, color values, icon files, design assets, and reference images. But traditional clipboard managers treat everything the same way, making it hard to find that perfect shade of blue you copied an hour ago.

PasteRheo transforms your clipboard into a visual design library with intelligent color detection, rich previews, and organizational tools built specifically for creative workflows.

Smart Color Detection & Management

PasteRheo automatically recognizes all major color formats and provides instant visual feedback. Copy any color value, and it knows exactly what it is.

Supported Color Formats

HEX: #3B82F6, #F59E0B
RGB: rgb(59, 130, 246), rgba(245, 158, 11, 0.8)
HSL: hsl(217, 91%, 60%), hsla(38, 92%, 50%, 0.8)
OKLCH: oklch(0.7 0.15 250) — the modern perceptually uniform color space

When you preview a color in PasteRheo, you get:

Large color swatch for accurate visual reference
All format conversions — instantly see HEX, RGB, HSL, and OKLCH values
One-click copy — click any format to copy it to your clipboard
Color harmony suggestions — complementary, analogous, triadic, and split-complementary colors
