On another note, I've always liked to visualize many of the various buttons and blinkies as having a narrow band holgraphic effect visible only to the operator immediately in front of it. Holographic labels that float above each button and refresh as the panel is reconfigured for various functions. Sulu sees things a camera off to the side can't see. It also gives a reason to the black console surfaces -- luminous type would read more easily if projected over a black background. Unlike the JJPrise, the REAL Enterprise took ergonomics and eyestrain into account.
I always saw it simply as them having such advanced
Starfleet training that all they had to do was look at different combinations of lights on the screen, and they could immediately interpret and understand what they meant.
Kind of like a visual form of Braille or something. If the blind can somehow interpret and make sense of different arrangements of bumps on a wall, then surely the TOS crew could do something equally impressive with lights in the 23rd century.
