Color palette extraction
Pull hex codes from a single thumbnail or an entire channel.
Thumbsy can extract a color palette at two levels: one thumbnail, or every recent video on a channel.
Single thumbnail
Open a thumbnail's context menu and click Get color palette. A panel appears at the bottom-left of the page showing:
- Six dominant colors, with a proportional bar showing how much of the image each covers
- Role labels — Dominant, Secondary, Accent
- Hex codes for each swatch
TODO: add image — Color palette panel with swatches, role labels, and hex codes
Click any swatch to copy its hex code — a checkmark confirms the copy. Click Copy all hex to copy every color as a JSON array at once. The panel dismisses itself after 20 seconds, or you can close it manually.
This is a free feature — no account or Pro subscription required.
Whole channel
On any channel page, click Extract colors in the channel's action bar (next to Subscribe and Share).
TODO: add image — Extract colors button in a YouTube channel's action bar
Thumbsy scans up to 24 of the channel's most recent videos and clusters their colors into a palette of up to 16 swatches, shown 8 at a time.
TODO: add image — Channel palette modal with progress bar and resulting swatches
From the results modal you can:
- Click a swatch to copy its hex code
- Click Export CSS variables to copy a ready-to-paste
:root { --color-1: #...; }block - Click Copy all hex to copy every color as JSON
Useful for matching thumbnail design to a channel's existing visual identity before you design a new one.
