This article was interesting, because color is one of those things that I like when it is done well, but I don't like when it is not, although I couldn't tell you why. I see so many advertisements, projects, and things at work that are done horribly because of the color scheme used. Visual rhetoric is just as argumentative as text when it is done right, but can be just as detrimental when done wrong. For example, if I see any neon on a webpage, advertisement, anything really, I automatically trash it or close the webpage. I hate neon.
Another place I often see awful color schemes is on powerpoint presentations. There are pre-made templates for a reason. Use them! Don't let your powerpoint look like this:
I realize this was a bit of a rant, but I am really looking forward to the facilitation on color. It is something that we use and look at every day, but (at least for me) don't really understand.
