Color Filter

ColorVeil adds a customizable color filter over your Desktop, Internet browser, video player, document, email, or program. You can work, play, read, write, or browse as usual.

Dyslexia / SSS

ColorVeil can help people with Dyslexia and Scotopic Sensitivity Syndrome. It applies a coloured tint across the screen, that can match the prescription from the optometrist.

Extra Dimmer

ColorVeil can reduce screen brightness, even below its lowest available setting. This helps you reduce eye strain, especially at night, and may help save battery on notebooks and tablets.


ColorVeil lets you easily customize the filter color and opacity. For example, choose Orange to block out the blue light responsible for sleep deprivation.

Easy On/Off

ColorVeil makes it very easy to instantly turn the color filter on and off: simply click its icon in the notification area. Or press a (customizable) keyboard shortcut.

Portable & Installable

You can run ColorVeil on any PC without installation: just download and unpack the ZIP archive. And you can also install and deploy it across your network using the MSI setup.

"We have been looking for the last few years to support children and young people with Dyslexia / Scotopic Sensitivity Syndrome by way of coloured overlays, but have never been able to find a solution that works on computers. ColorVeil gives us the perfect solution, allowing full customisation by way of overlay to match the colours stated by the optometrist, removing a significant barrier to that young person's learning."
