Watery Grave death color change?

[batsrcool]

I was making a ghost in CAS, and I noticed that the Watery Grave death - which was originally the same color as the drowning death - has had its color changed to a deep blue color. I checked the list of changes in the update, but this wasn't mentioned in it. Is my game having an issue, or did they actually change this?
Here's some pictures.

No I think that's one of the undocumented additions.  It's like that in my game.
