But what about highlighting? Or different colored text?
There are a lot of good reasons to use color. Primary to those of us in education is the fact that color conveys information. More information in the same amount of space is a very good thing.
But very few labs, worksheets, handouts, books or even websites that I come across use color to convey information. We’ve all grown so used to the limitations of a a 19th century printing press that we have just accepted them as reality. (not an uncommon problem)
I should commit to a plan to increase the amount of color used in handouts and labs next year, but as I mentioned above I’m not even 100% sure of the best way to use it. And just saying that I will use some artificial number of colors on each document seems…well…a little artificial. I wish someone smarter than me would add color to The Elements of Style and be done with it.
