ColorVeil ( is an assistive technology. It is a totally free software programme that allows the user to create the effect of placing a film of any colour or depth of shade over their screen.

What’s the point of that? Well, many individuals with dyslexia, Scotopic Sensitivity Syndrome, as well as many who are neurodiverse (such as those who are autistic and/or have ADHD) find the use of colour filters helps them with reading, reducing eye strain, reducing colours or brightness that they find distracting, irritating, etc. In general, for some, looking at things through coloured lenses helps. ColorVeil recreates this for computer screens but has a number of advantages.

  • The range of colours/shades is only restricted by what your screen can generate.
  • The opacity of the filter can be anything from 0-100%.
  • Pick your colour from typing a name or selecting from the colour map.
  • Switch it on or off via a customisable short-cut key or from the taskbar icon.
  • Multi-monitor/multiple display support.

ColorVeil interface, with colour picker window.

The advantage of being able to quickly switch it on and off easily, means it can then be used on shared machines and switched on whenever the individual who needs it wants to use the machine and switched off for other users when necessary. Something that regularly happens here 🙂
