Eye color has to do something with your soul, like when Peter said,  when you kill someone innocent something will be taken from your soul and your golden eyes will become a metallic blue. But Theo is a Sociopath, so when he killed someone his eyes stayed the same,  because he doesn't regrets it. So I thin Kate and Mr. Douglas are Psychopaths, and that's the reason why there eyes are green. But, yeah it will probably be revealed this season.
