Curve colours in 2-D plotting

I'm finally going to start my MaplePrimes blog, and I will post answers to some of the questions I get about the areas with which I'm familiar. Most of time, I get asked about 2-D plotting. Some of the information here may be repeated from forum comments, but hopefully, this will make it easier to find. Unfortunately, my participation on MaplePrimes comes in spurts, as I try to find time between my other tasks, such as developing features for new releases. I tend to rely on the many Maple experts on MaplePrimes who very competently answer most questions that arise. I will, however, try to be diligent about adding a new tip at least once a week. Let's see if I can live up to my promise and get beyond this first post! I've been asked, "How do I assign colours to different curves on a plot?" If you provide a list of expressions as the first argument to the plot command, you can also provide a list of colours as the right-hand-side for the colour option. This is described on the plot help page. Maple uses a default list of colours to assign to curves generated by the plot command and you can view this list by issuing plots[setcolors](). The plots[setcolors] command was added in Maple 11 and you can also use it to change the defaults. If you try the examples on the plots[setcolors] help page, you may see colors unfamiliar to you if you're a long-time user of Maple, like "LimeGreen" and "MediumOrchid". In Maple 11, we made available many new colors and these are listed on the plot/colornames help page. Note that the new color names are strings. We went this route to reduce the potential for conflicts with assigned names. The plot/colornames help page also shows mappings to the former color names (which are still accepted).
