Multiple Arrow Different Color?

[codevarun]

Hi,

I was reading a blog in which I found that you are using multi colored arrows for multi arrow. But when I did the same thing, I can only see one colored arrows. Can you please let me know how to do it?

The second screenshot has more complicated case of multi arrow.

Ideally, I would want green for my side, red for other side - (DroidFish has blue for our side, green for otherside)

Possible?

I don't want mixed colors - perhaps engine configuration can have multi-colors one for playing side, second for waiting side?
