Set background color in Oracle Forms

Hello to All,
Good Afternoon,

I would like to ask for help if this is possible in oracle forms?
I want to change the color of Text Item field by using Button Trigger.

If the button will be pressed, the color of Text Item field will be changed.

If it is possible, please advise and teach how to do it.

Your help will be much appreciated.

Thank you.

Regards,

Gerard
