Good stuff.

quick q: why do you call this a hopfield network? I see you have a fully connected 2 layer neural network (0 hidden layers): https://github.com/mateogianolio/hopfield-color-recognition/...

instead of a bunch of circularly connected perceptrons: http://en.wikipedia.org/wiki/Hopfield_network#mediaviewer/Fi...

p.s. it looks like the library you're using has a built in Hopfield network `new Architect.Hopfield(10)` (at the bottom: [here](https://www.npmjs.com/package/synaptic)), why didn't you use this?
