Change all button colors at once?

Hi folks,

Trying to change all button colours at the same time from an event, eg

Button*.color = 0,0,0 where * is a wildcard for 30 buttons.

Doesn't work though, also tried:-

for x = 1 to 30
Buttonx.color = 0,0,0
next x

Doesn't work, is there a wildcard or way to select all buttons for change at once?

Thanks.
