Multi-Colored (Rainbow) Solder Mask?

I am looking for information about multiple soldermask colors on the same PC board.

I saw a photo of the back of the Rainbowduino board that had multiple solder mask colors.

Is this something that most PC board manufacturers can do (given the proper soldermask files)?

Who did the Rainbowduino?

Thanks,
Mike

hi there,
sorry,we don’t design Multi-Colored solder mask for a long time, because it is hard to processing and the cost is expensive, so less people use it and few manufactory do it now.
