Grey: Grayscale & Website Color Filter by Edward Doubovik

A little less color. A little less noise.

grey reduces website colors for a calmer browsing experience. Keep things simple with grayscale, or choose a gentler level of color reduction in Settings.

• One-switch control: Turn grey on or off from the toolbar.
• Safe Zones: Keep selected websites in full color.
• Five-minute breaks: Temporarily restore color on the current site. Color reduction returns automatically.
• Optional intensity slider: Choose how much color to remove, from 0% to 100%.
• Optional Slow Fade: Gradually reduce color on selected sites over ten active browsing minutes.
• Optional hover reveal: Hover over an image for two seconds to temporarily restore page color.
• Optional browsing stats: View approximate daily and weekly time spent browsing with color reduction.

Apply grey across websites or limit it to a list you choose. Extra controls stay in Settings, keeping the popup simple.
