There is no control of type ‘Titles’ but from your description I assume you mean CvsTextField controls.
When I created canvasGUI my priority was to provide a range of colour schemes for users to choose from so they could quickly create an attractive GUI and then get on with the code logic needed for the actual sketch.
So at the moment it is not possible to change the colour of individual elements of a control, including font colour.
There seem to be two options
- add functionality to change individual colour elements on a control-by-control basis
- enable users to create and apply their own colour schemes, probably using one of the predefined schemes as a starting point.
I have not decided on which approach I might take as I need to consider how it will affect the current implementation and the user experience.
