... To see how this is done, it helps to visualise the colours as points inside a cube with edges 1 unit in length. ... The task of allocating these colours is equivalent to constructing 256 boxes inside the cube, each box to contain a subset of the thousands of colour points. ... At present the boxes are allocated so that they all tend to be of equal size, but it may make more sense to allocate them so that they all tend to contain equal numbers of points. ...
