I want to:
1. Have matplotlib assign the linecolor for a plot
2. Read the linecolor with .get_color()
3. Create another plot with the linecolor set to a lighter version of
the previous linecolor.
a, = plot(x,y)
a.get_color() = 'b'
b, = plot(x,y, color = "#xxxxxx")
Since I'm only using the standard matplotlib assigned colors which
cycle through b,g,r,c,m,y,k I thought I would just create a mapping
between each color and a lighter version.
How do I get the hex or RGB string for the base matplotlib colors?
Also, if there's a different property I can use to lighten the line
color without changing the color that would be cool too.
