Green Cobalt(II) hydroxide in D2O

I reacted Potassium metal with Deuterium oxide in order to yield a basic solution of Potassium deuteroxide. I then added Cobalt(II) chloride to precipitate Cobalt(II) deuteroxide. It has been 2 days already and my precipitate is still green. Why do you think this is?
