Sorry that you do not like the color in the third edition of Linear Algebra Done Right. Most students find it useful, for example, to have definition boxes be a different color than theorem boxes. The color did not increase the price of Linear Algebra Done Right. New hardbound copies of the book usually sell for about $45 on Amazon, much less than most competing books. Furthermore, Linear Algebra Done Right almost always has the best Amazon sales rank of books for a second course in linear algebra. --Sheldon Axler

I have nothing against using color in books. I think that, for example, Topology Illustrated by Saveliev got this right. The use of color is especially helpful in presenting objects (not text) when the density of information is high, e.g. in schematic images found in books on cell or molecular biology. Turning an otherwise excellent text into a shiny toy, on the other hand, only serves to damage its reputation in the eyes of a serious reader (but, sure, not necessarily a younger student who may be used to or even appreciative of shiny things).
