Hi,
How easy do people think it would be to write a colour tinting
extension for the benefit of those with Irlen Syndrome [1]?
The *functionality* is available in the gnome shell magnifier in the
upcoming GNOME 3.6 release. One can change the brightness and contrast
of each of the R, G, and B channels. What's missing is a GUI to do this.
You can try it out (after enabling the magnifier) by using gsettings
from the command line. For example:
gsettings set org.gnome.desktop.a11y.magnifier brightness-red 0.75
This will result in a reddish tint.
The relevant gsettings are:
brightness-red
brightness-green
brightness-blue
contrast-red
contrast-green
contrast-blue.
The values range from -1.0 to 1.0, where -1.0 removes the contribution
of the channel, 0.0 means "no change", and 1.0 sets it to the maximum.
Be careful: it's possible to end up with an colour combination that
makes the screen contents impossible to see (yes, there needs to be a GUI).
Would this suffice?
