Alternate row colors

[Breezy]

Hi,

I have my headings as blue since "Frog" is chosen. And when "Frog" is not chosen, the table headings change to green:

=if([Frog/Bug]='Frog',RGB (30,144,255),RGB (124, 252,0))

However, I want my rows to alternate grey and light grey, regardless of if "Frog" is chosen or not. How do I make it look like below?

Frog

Ok, good to know..

I used the formula you recommended. It looks a little funky though. Any ideas?
