Hi Smiljan,

I can suggest two options:

• build an entire custom theme that matches the overall colors you want to have
• add the appropriate CSS rules to also cater for hover and selection states, you can see a basic example here

A simple plain parameter would not suffice for such a thing, because things quickly snowball - what if someone wants to change only the hover or only the selection, or only the main and selection but not the hover color? The combinations are simply too many for declarative control, and this is why styling should be done with appropriate CSS rules - this is the general way this is to be done in a web application. Thus, I am going to have to mark this as "declined".
