A shape is made of different colors which are mapped to user color
combination colors (e.g. if a shape use the #3AADAA color, it is by
default mapped to color combination background color n°4). We allow
to change that arbitrary mapping for each shape should a theme want it
(for example so that its built default page can use that shape with
a different color without having to hardcode it).
