Black and White

This strip started with the idea of someone not knowing how to change colors in a Powerpoint presentation. So, what if they used black font on a black background, or white font on white paper? I noticed that a trned line did not show up well the other day on a presentation, so I tweaked the color to be lighter. Since I wondered, "What if I did not know how to do this?", I came up with the basic format for today's CoV.
