That's great, and if I was to do the opposite, everything above half to turn green, how would the formula look like? Sorry but I'm so new to this 🤦

You would change the less than sign "<" to greater than ">" in the formula and click on "Format" to modify the background color.

  And if A1 was exactly half of A2 for example,
  A1 11
  A2 22
  
  Would I show it as
  =A1<>A2

    No, the "<>" symbol means when A1 does not equal to A2. To get an exactly half condition would mean adding the "=" to the greater/less than sign.
    
    For example, if you want A1 less than or equal to 1/2 of A2, the formula would be:
    A1 <= A2/2
