A/C cooling issues.

[JoeBoxer1130]

2003 Chevrolet Tahoe,
Does anyone know if the AC lines are supposed to be like this? I tried to photoshop the picture of my situation. BLUE arrows are COLD to the touch, and the RED arrows are HOT.
I'd like to know if this affects the temperature inside while the AC is working. I wanna assume the freon isn't empty because its blowing cool air but not COLD enough.
Any tips or help will be greatly appreciated.

So the temps are in the right location. Gauges are best in determining charge. Where that green line is defines where the orifice sits. High pressure liquid (red) enters the orifice and flashes to a gas in the blue line, which is your cooling effect. The blue line goes into your interior hvac system which contains the evaporator. This is like a radiator that removes heat from the interior (cooling the air that passes over). That cold line should feel like a cold beer, about 38°- 43°. Check your cabin filter behind the glove box, if it is clogged you get no air flow, then make sure your blend doors are working properly. The blower motor has multiple speeds, if it's stuck on low you could have a bad resistor.
