The beetroot seeds are a "Quattro" mix, which is supposed to produce 4 different colours - red, white, yellow and red/white stripes. I've only had red ones and the white one so far so I think the others may have been more reluctant to germinate. It's difficult to tell them apart from the plant though.
I've also avoided "funny" colour beans or the same reason, although I do grow yellow courgettes!
