What is the color of Joey the ghost?

I'm trying to post something on the forums on http://www.wadjeteyegames.com but for some reason the developer seems obsessed with people knowing about his games. In order to post my question I need to answer a couple of questions about games they have made. Most aren't hard, I just need to search a bit online. But I keep running into the question of what color is Joey the ghost. I checked youtube and he seems to be gray (or grey, depending on how you spell it) but neither worked. I tried purple based on his suit and that didn't work. I tried white figuring he was originally pale skinned in life. Nope.

I've not played the Blackwell series, the question I'm trying to ask is about Unavowed. Any suggestions please?

I'd say blue, but I haven't tried posting anything on the official forums yet
