Adjustable Color Filter

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.
