The back of my throat is more pinkish red n the front of my throat is just pink is this normal. Its been like this for a long time now.?

Possible. The back of the throat is usually pink to red in color and it can look more red than the front aspect. Sometime, you can see red bumps which can also be normal. Keep in mind that the back of your thoat is in constant exposure to variable chemical, food, hot/cold drinks, infections, etc. Unless you are having symptoms like fever, coughing, pain in the thoat, you should be ok.
Probably normal. If your throat doesn't bother you (other than how it looks) then it is most likely completely normal.
