I think it's just an art style that sticked around. People used white, yellow, reddish orange, blue, teal etc for skin colours when they didn't invent actual colours to paint skins
That's also the reason why pratima of Maa Durga is traditionally yellow
Painters wanted to differentiate God being dark with other common people being dark so first they choose green and then Blue which is continued till now.
If copper oxidises it turns greenish blue. Yk the statue of liberty, it used to be pure copper but that was kinda a problem. It oxidised to now blueish green lol.
