GWX3GOLD - strange yellowish/pink lights below deck

[Paul Riley]

I think I noticed this last night actually,but I have noticed the lights inside the UBoat have a sort of yellowish tint to them,and some even border yellow/pink,especially over the Chief Engineer's head (type IIA),as opposed to the usual white light I am so used to.Red lights are still the same at night I might add.
Now this is not a major problem,just a small cosmetic observation.Is this normal,and if its NOT how do I rectify it other than returning to port and disabling mods.Could it be linked to the open hatch mod?,as I have just enabled it for my 2nd patrol,then realising its pointless in a IIA as there are no seperated compartments.

Thanks
