Photoshop Extension Panel Button Question

[IanBarber]

I have a panel with a button and when pressed, the button changes to a colour of my choice.

Question:

Is it possible for the button to remain that colour when I start working on a document in photoshop ?

I have tried several ways with CSS but as soon as the panel loses focus, the button colour also goes away
