Hi Greg,
There’s been a big debate about Tamaru’s colors lately. You can read it on Bionicle Maskposting | I think we've been lied to all along about Tamaru colors | Facebook
He looks yellow-green to me on the CGI render and his colors are not similar to those of Kongu, which he’s supposed to have: https://i.imgur.com/M6x63Ij.png

So basically the question is - are his colors yellow and green? CGI renders were made by LEGO, and feel more canonical than MNOG games.
