Oh looking back at the EEVBlog review, it was actually him who said this, at 10 minutes in. He says, "The colour coding doesn't make much sense e.g Purple for input voltage and output power." Basically the coloring of different things on the menu seem a tad random. It's really isn't a huge deal, though, more of a stylistic thing I suppose. I installed the latest version of your custom firmware and the units for each of the outputs seems to be below the number, for example the V doesn't align with the numbers, but it's slightly below. I don't know if this was on purpose or not and it's stylistic, so it doesn't matter that much.
