In that way it will be easily modified through the palette of themes such as Windows8, Windows8Touch, Office2013 and VisualStudio2013 and it won't be needed to overwrite the whole template. That feature is very important for users with visual impairment or where low contrast screens are used.
Hello Stefan, Thank you for your feedback. If this feature request accumulates enough demand, we will prioritize it and introduce such a property for other themes as well. Best regards, Dilyan Traykov
It would be great to have this feature as it exists in the Green theme. There are customers we have who have big difficulties to read the disabled text, especially on some types of monitors.
This is to let you know that such property is exposed in our new Green theme.
