Selecting different colours for categories when drawing graphs

I recently needed a set of colours for color coding a diagram (this one). The wonderful d3.js has several colour schemes but they always top out at twenty colours. After googling around for a while I couldn't find anything good so I wrote a generator instead. Here's what the first version looks like:

You choose two lightnesses and a grid density, and it selects colours one after another and prints them out.

This was OK but I wanted a bit more flexibility in the preselection of colours, so I wrote a second (more complicated) version:

The second version allows you to specify any filtering function on which colours are allowed. So you can, as in the above example, choose from all colours that are a certain distance away from another colour (for consistent contrast).

Both versions operate in "LAB" space (as explained in the About section of the second one) so that the colours are spaced by "perceptual" distance -- the distance between two colours is directly related to how different they look to a (typical) person.

Each time the generator chooses a colour, it chooses the one that is furthest away from all the previously selected colours. This means that the first few colours are very different but as more colours are added they get closer together (because there isn't any other option).

Here are some other examples from the (second) colour generator:
