I basically do that when I create spreadsheets (having extra columns for sorting), but I regularly receive files from MS-Office users who tell me “just sort by the color” and it is tiresome explaining every time that my tool cannot do that. They are not trying to annoy me, they just use their tool the way they always do.
Please allow me to quote somebody else:
[…] the answer to “Train has overturned, people are trapped” is not “Train is designed to be operated in an upright fashion”. Highlighting names by background color is a natural way for people to work.
