Features & Capabilities

Zen Thumbnails is a utility for users who want to use YouTube without the visual noise of modern thumbnails. It replaces video thumbnails across the site with solid, low-saturation colors.

The color for each video is generated by hashing its URL, meaning the assignment is deterministic: a specific video will always have the same color every time it appears on your screen. This maintains a sense of visual consistency while removing the distractions of high-saturation images and engagement-bait tactics.
