Someone failed the color discernment sections of the IQ test, huh?
What does color have to do with it? Whether or not you realize it, you have a chart -- or, if you prefer, a spreadsheet. Spreadsheets are laid out with columns that have headings, which are
supposed to describe what the entries below represent. Your first entry under "Cartridge Type" is "Bolt Action."
Trying to use colors as a way to make a two-dimensional chart present three-dimensional information is confusing -- which is why I said I don't understand it. I don't.
