The human-sized SerpentO.R. did have a jaundiced, sea-sick green color for his face. However the inspiration for the deco on the Club figure was the Transformers-sized SerpentO.R., after he was upgraded by the Matrix.
And that version of the character does have a silver face.
As for the character bio card, I've seen some fans wondering about that. Obviously you can ignore it and use this figure as the original SerpentO.R., but since no one wanted to interfere with anyone else's fiction, I tried to take elements from the Devil's Due origin and reshape them to fit the Wingsverse. Where Fun Pub was using the character. So since the story beats for SerpentO.R and General Hawk were intertwined in GI Joe vs. the Transformers, I had them quite literally intertwined again here. Also with SerpentO.R.'s nebulous faction in the original story - built by G.I. Joe, but turned evil, lead the Decepticons, then stole the Matrix, and became slightly heroic in that he would destroy himself to stop his own nefarious plans - I thought using General Hawk as a way to bring SerpentO.R. back from the side of evil worked well. Especially since General Hawk is all too familiar with becoming part of a Cobra-designed science experiment gone wrong (Venomous Maximus). Add in a few references to the synthoids and Old Snake from Sunbow/Wings, and it seemed like an interesting mirror of the previous story line. Jim Sorenson then took all those ideas and I thought he crafted a very cool bio.
And although it doesn't touch on his origins all that much, you can see the Club's SerpentO.R. in action in
Timelines #9.
