How to compare two colors for similarity/difference
...d).
Three components of colors can be assumed 3D coordinates of points and then you could calculate distance between points.
F.E.
Point1 has R1 G1 B1
Point2 has R2 G2 B2
Distance between colors is
d=sqrt((r2-r1)^2+(g2-g1)^2+(b2-b1)^2)
Percentage is
p=d/sqrt((255)^2+(255)^2+(255)^2)

If elements are always nearly sorted as in your example then builtin .sort() (timsort) should be fast:
>>> a = [1,1,2]
>>> b = [1,2,2]
>>> a.sort()
>>> b.sort()
>>> a == b
False
If you don't want to sort inplace you could use sorted(...
