The Two New Style of masks do Have parts that CAN be dyed. On the jester Mask it is the blue side of the hat, on the Porcelain Mask it looks like the colored parts of the mask like the cheeks and nose and stuff can be dye.
HOWEVER there are some masks that Mesanna had painted special colors and those are rare colored hand painted masks, they are painted by Mesanna.
If someone is trying to pass off any other mask, not hand painted by Mesanna, there is NO way at this time that they are rare colored masks, so do not be fooled.
If you are on ATL and need some named masks to fill out a set look at my posts on the atl trade forum and see what i have extra I will be parting with all my extra in the near future.
