in the original code, seems there is a check of colors in this branch, so does it mean after this refactoring, this won't happen? or colors shouldn't be a str in the first place once reaching this part of code?

if isinstance(colors, str):	
     colors = list(colors)

Right, in this particular function colors will not be a string. This check is effectively carried out in _get_colors_from_color.

if isinstance(colors, str):
colors = list(colors)

return colors[0:num_colors]
