[Matplotlib-users] Possible to change MPL color scheme?

Hi,

I read previous mail about "colormaps" which reminded me to a question
I had about MPL colors.
Colors in MPL plots are dark, and pale, and not is some specific color
theme but it's just pale dark.
I thought that usually people make plots brighter (as more attractive ;) )

If you can, have a look at this plot I just made, and same image with
same named colors as set by CorelDraw for example:

As you all probably know cyan is not cyan but teal, and green is with
50% green, and every color is not as expected, except red and blue.
I don't know much about color systems and color space, so thought to
ask why is it like this and if colors can be somehow differently
defined at user end?
