Request: change color of model

[stan0033]

I got this model from hive and edited it in model editor, but I cannot find a way to make it green-ish. Can someone do it for me or tell me how it's done? When it's unanimated it's grey and when i play an animation it is blue(??). The only green thing is the decay of death

It's the geoset animation
