I kinda slightly disagree that if you have time to tone everything you have time for color. My toning takes about 3 or 4 hours per page, my inking takes about 5 and pencils take about 3, so I'm looking easily at 10-12 hours per page.In order to update more than one page a week, (I do two or three) I have to work 20-30 hours a week. That doesn't count the layouts, roughs and such I do for future pages too, and the second tutorial based series I do.
Why would you color without toning? I mean toning is just like shading, so adding flats and shading will take more time than "just" toning/shading. Lots of us here work too, so combined with a full time job and a comic, say at least 2 or 3 a week, that's almost 2 full time jobs and killer on anyone physically.
Maybe I am different than others in that I consider toning to be a whole different process that coloring?
However you are spot on though @joannekwan that color can turn me off of comics. I have had a few like that.
