None. Just look at them.

“Every Ball is indentical in every way”

2 weighings and 3^n balls can be solved with n weighings.

Except one's lighter. (in color)

I throw the balls at the adorable puppies wanting toys off screen

For lightness in weight, if you're lucky, you'll just need one weighing. Put three on each scale, and the seventh might be the odd one out.

wat if it isn't?

Gotta be more precise, Frank.
What do you mean by lighter? In color or brightness or weight?
WDYM by least required? Possibly, or in every case?

3 balls weighed against 3
if both are equal, the remaining is the lighter ball
else choose the lighter side 3 balls
check for 1 ball against 1 ball
if equal, the third ball is lightest
if not the lighter side is the lightest ball
So 2 tries at max
