At the moment in inventory listing if a stock item is in a stockroom, it's lit
up in red. Which is great, it makes it stand out.
Each of my stockrooms has a different purpose, and I really don't want to accidentally
list anything from stockroom A for sale, as that's the stuff that I'm having
some trouble with (stock count wrong), or have pulled (an indeterminant amount
of) for personal use or other problems.
I would like each stock room to have a distinct color. The colors used ought
to take into consideration the various kinds of color blindness (I suggest lightred-lightblue-darkgreen).
