MIL-STD-2525 does not mention it, nor does ADRP 1-02.
JP 2-01.3 illustrates a K in a purple circle, but no number.
ATP 2-01.3/MCRP 2-3A illustrates a Kn or Dn (where n is the corresponding number) but is absent of color.

Shouldn't it be a purple K or D, and a corresponding number, inside a purple circle? Why or why not?

FM 34-130 Intelligence Preparation of the Battlefield & FM 101-5-1 Operational Terms and Graphics are your (initial) References.

The "Purple K" is correct. Since it is LOCAL Commander based, the Numbers "may or may not" be present.

The MIL-STD-2525 works in conjunction with the above but applies to Units/Equipment/Facilities as opposed to "overlays" (not a perfect explanation, but go with it).

The color should depend on whose side it is on.

As you can see from the imagery, the key terrain for this mission is the enemy fuel resupply site. That's right, people, our objective is the circle K.
