Air Conditioning recharge question

I have a 2015 Limited with around 43,000 miles. The air doesn't seem quite as cold as it should be and I'd like to add some 134. My question is which line is the low pressure. In watching some videos it suggest the larger line is the low pressure line but the connector on the hose fits the smaller line fitting which has a white dab of paint on the cap. I checked the caps on both lines and don't see any reference to high or low pressure. Any help would be greatly appreciated. Thanks!

Can't remember large or small but if you got one of those quick charge cans from the auto parts store it will only fit the correct fitting since they're different sizes for low and high side.. Can't get it wrong.

The low pressure side is the smaller fitting.
