How do you add HDR colours to text?

I want to add the bloom effect to some text in my game. I have post processing set up and it will apply bloom to any HDR colour above intensity 1.5. I need to add an HDR colour to the text. The ways I think it could be done are by editing the text script to have an HDR colour picker, or adding an HDR material to the text. The problem is that I don't understand the text script and all materials I add make the text disappear.
