Feeling Evaporator Hose in and out question

Year: 1993
Make: Ford
Model: f-150
Engine Size: 4.9l
Refrigerant Type: 134 convert

Hey guys got two quick qestions:

1>what color orifice tube should be in my system? I think I might have gotten the wrong color at the "zone".

2>I also would like to know if the "feel the inlet outlet" hoses on the evaporator are the best way to tell if system is charged properly? Is it when they are equal in feel temperature?

If the inlet and outlet temps are the same as measured with a thermometer (either contact or IR), the charge is close. I usually add an OZ after that.

Best way to charge a system is by weight. The method you describe can be used to verify a proper charge level.
