Yes, that's it. Which reminds me of an anecdote from the early days of color television i.e. in the testing phase, probably at the Sarnoff lab. The camera was focused on a bowl of fruit in a lab remote from the one in which the other equipment was set up. The technicians could not get the matrix set right no matter what they did (twiddled pots in those days). They could get all the fruits in the bowl looking except the banannas correct but when they did that the banannas looked blue. If they got the banannas anywhere near correct everything else was way off. Turns out, of course, that some wag had snuck back into the lab and substituted a blue bananna for the original.
