One thing to keep in mind is that the level up OP-Code may not be inplace, so when you level you MAY need to zone to update your level info, so that con colours are correct for your new level.
That being said, and my lack of a 65 to test with (61 highest atm), I'd have to agree with uRit1u2CBBA='s code change, making the last check < 66.
It was my understanding from Sony's patch message that when they changed the con range, it was to keep the same range (i.e. greenRange & cyanRange in our code) that a 60 has through 65. So at 65 a 44 should be green while a 45 cyan (light blue).
