Roughly 1 in 12 men and 1 in 200 women experience some form of color-blindness. Most websites, however, are designed for the trichromatic majority. An adjustable color filter extension lets users compensate in real time:
Protanopia / Deuteranopia support – Boosting the red or green channel can restore contrast between traffic-light indicators, status badges, or data-visualization legends.
Tritanopia work-arounds – Increasing blue saturation or toning down red–green noise helps users detect links, chart lines, and error banners often coded in hues they cannot otherwise distinguish.
Bright white backgrounds and high-intensity blue pixels contribute to digital eye fatigue, especially after sunset. A colour-filter overlay addresses this problem far more flexibly than a blunt “dark mode”:
Blue-light attenuation – Sliding the blue channel down 30–40 % mimics warm, amber night-shift modes without affecting system-wide colour fidelity (handy when editing images in other tabs).
Low-contrast boosting – Raising overall saturation or selectively lifting mid-tones lets users who struggle with light sensitivity read pale grey text without zooming.
The change is reversible in a single click, making it ideal for users who switch between work tasks that demand crisp colour accuracy and evening reading that benefits from warmer tones.

- (2025-06-04) Timothy Monk: This does EXACTLY what I was looking for! It applies a simple RGB colour filter over the page while preserving black. Every other colour filter I could find applies the colour as an overlay, so black gets washed out, and dark-mode filters usually invert the colour of images, but this one is actually useful. My only issue so far is I'd love something like a colour-disc to set the filter, rather than just the separate RGB sliders. It would also be nice to be able to save presets
