Turn YouTube into your own cinema. The colors of the video softly spill out across a dimmed screen. Meet Afterglow — ambient light for YouTube. ■ NEW: Afterglow (ambient light) • Picks up the video's colors in real time and spreads the glow across the whole screen • A sunset fills your screen with orange; an ocean turns it blue • Colors are mapped to where the video sits, so the picture seems to extend past the player • Pauses drawing when the video is paused or the tab is in the background — lightweight by design • Combined with Focus Mode dimming, it feels like bias lighting behind a TV ■ Dim distractions — don't delete them • Dims comments, recommendations and sidebars • Nothing is hidden, so you can still glance at them when you need to • Background brightness adjustable from 0 to 90% • One click, or Ctrl+Shift+T, to toggle ■ How it differs from YouTube's built-in ambient mode • The built-in mode is a faint glow right around the player • Afterglow dims the whole page and spreads the light much further — the glow actually stands out • It turns off the built-in ambient mode automatically, so the two never double up ■ Also included • Picture-in-Picture (Ctrl+Shift+P) • Choose your shortcut key: T, F or Space • Available in 11 languages ■ Perfect for • Lo-fi and background music while you work • Movies and live concerts at night with the lights off • Study videos without getting pulled into recommendations • Music videos and nature footage as mood lighting for your room ■ How to use 1.
