"Disabling YouTube's Ambient Mode Colors for Fullscreen Videos: A Step-by-Step Guide"
YouTube has introduced an ambient mode that brings on-screen colors to the black edges of fullscreen videos, but some users find it distracting.

The colored edges will then return to black, providing a more traditional viewing experience.
