I have to print a ton of articles for class and I don't want to waste all my black ink. I know all the other colors use black to make it up, but I want to know which one(s) uses the least.


Answer:
white

the other colors can be combined to form black, but if you print text in yellow or magent, it doesn't use black. depending on your printer, when one of your colors is empty you have to get a new color cartridge, and they mostly are more expensive that black ones.
so better stay with black.
