Hello jowens1126,
Thanks to Parts and Service and the Sales Division each calling the same code different names, identifying some colors by name can cause confusion. Sales had tried to make some of the colors sound more upscale by dressing the names up on certain car lines. The color you are looking at on a '71 is "3" Bright Red. For '72 and up the code changed to "2B" but is the same color red. The "T" you mentioned is "Candy Apple Red"and was a little darker red used on certain full size Fords, F and E series and Bronco trucks. The Ford number for 3/2B is 3560 and T is 2008.
