Button colours

Hey Noda,

Sorry for putting in so many tickets on the same night. 🙁

I am curious if you could tell me how to use a custom colour for the button elements? (see attached)
Just in case

I need them to be a specific colour and I can’t seem to figure it out :'(

I look forward to talking to you soon.

Cheers,
Ash
