Drywall "fainting curves" issue

[WillieWoe]

This drywall can go together with drywall "fainting stripes" to make more interesting patterns, but! There is an issue: the "fainting curves one, when you hover it and before it's built, has the colours flipped in comparison to once it's built. Basically the dark stripes of the pre-built one become light stripes after building and vice versa. This doesn't happen with the "fainting stripes" though, the darks remain dark and lights light (which is great). It's not a big deal ofc., but it is annoying having to rebuild the whole thing over.
