Usability and Themes

Half of mankind has some sort of visual disability including blindness, myopia, over sensitive or diminished eyesight, colour blindness, impaired field of sight…

Increase of resolution, contrast and fonts are helpful to overcome sight disabilities.

Changing to a gray Graphical User Interface might help in cases of colour blindness or even avoid epileptic attacks caused by certain colour combinations.

Theming was –still is– advertised as a remedy to every eye-ailment, except blindness. However, a working theme depends on all developers to support it. In itself an impossible claim! Even Operational System -vendors have frequently failed to properly implement theming in their own applications.
