About this extension
CupColors gives any football stream the colour and feel of a classic World Cup. Press play, click the ⚽ icon, pick a year — the look appears instantly. Click "Off" to go back to the original.

Each era is tuned to its real broadcast technology, not just a random filter:

• 2002 · Korea/Japan — soft, washed, cool tones of standard-definition TV
• 2006 · Germany — the first all-HD World Cup: clean, crisp, warm summer light
• 2010 · South Africa — bright, golden, saturated African-sun colours
• 2014 · Brazil — vivid tropical HD/4K, the sharpest of them all

Optional film grain + scanlines add an authentic old-broadcast texture — heaviest on 2002, off whenever you want. Just one checkbox.

Why you'll like it:
• One click, instant effect — no setup
• Works on RTVE, DAZN, YouTube and any site with an HTML5 video
• Follows the video into fullscreen
• Lightweight: pure CSS filters, no lag

Privacy: CupColors collects no data whatsoever. It only applies colour filters to the page you're watching and remembers your grain on/off choice locally. Nothing is sent anywhere.
