I have this Index, so I'm familiar with who's on the cover. And I may be misremembering this, but I'm pretty sure 10 Eyed Man was coloured properly in Crisis #12 and it may have been in one of the printings of the TPB where the mistake was made. Of course, he's hard to recognize without his costume and could easily be mistaken for a civilian. I know I did on my first reading of it.
