Like I said before, that guy below Rufus and Tseng is Kyara Weld or something. Besides, a look at him will tell you he's too old to be Reeve, especially predating FFVII.

Being in uniform means strictly following the uniform code down to the smallest detail. Even having your shoelaces untied means being "out of uniform."

I checked, and the colors I gave are correct. The Final Fantasy Compendium has plenty of pictures of Reeve and each of the Turks, including in-game shots as well as character art, so you can see for yourself. You can also use it to verify that Reeve is pretty young in FFVII, and a look at Vincent when he was a Turk will show you that the uniform didn't change between then and in the present. (Look under Characters, then under FF7 Characters.)
