What about the following workaround?

In[1]:=
<< "Graphics`Colors`"
greensTxt = {"CinnabarGreen", "ChromeOxideGreen", "CobaltGreen"};
greens = ToExpression /@ greensTxt;
Do[Plot[x^(k), {x, -2, 2}, PlotStyle -> greens[[k]],
     PlotLabel -> greensTxt[[k]]],
    {k, 1, Length[greens]}];

HTH,
Jean-Marc
