Would it be possible to add any darker colours? Particularly dark blue as that is the colour that i write and read on and it would be extremely helpful.

Works a treat. Couldn't get to work. This is brill!

Sue Dowdall


This is a great little extension, lightweight and non intrusive.
With dyslexia its reading that's an issue, not the underlying
intelligence. An aid such as this one, can help deliver the
world to some who may not otherwise have received it.
Great Work.
