clothespin couple

My favourite couple! Really, have to commend the pair's colour coordination. Or maybe that praise should be going to their god creator. Plus the winter garb evokes a sort of fuzzy, warm, bundled-up feeling between the two.

How do you colour these? Marker? Paint? Magic dust? Lavos' multicoloured ashes after Chrono et al. are done with his space-faring spiky ass?
