This video demonstrates a code module which allows you to change the colour of the selected option group label, and optionally collect the caption of the selected label.
This code module is generic, it will work for any option group containing any number of labels (within MS access limits) and will change the colour of the selected option group label, you could also modify the code to change the other features of the label, like the border colour, border style, text style, font size, any attribute which is modifiable in VBA code.
