Implementation ideas:

Given color points and order, fit spline to this
Points define a curve in LAB space
Preprocess this to get a curve with monotonic lightness: longest increasing subsequence?
Have a method that, given the points and a number of control points, finds the best quadratic spline to approximate these points
Binary search for the spline with the smallest number of control points that has reasonable error
