Yup, was all over that. Obviously though, there's a way that's been discovered to get the pattern "background" to be adjustable in color. Not the background itself, of course, but a solid shape on the first layer. However, even doing that it comes out pink despite being white in CAP and in my install screen. I get in the game, go into change, say a fabric, and it's a pink background. The color IS adjustable to a degree, but it's not the correct color (turns kinda orangey when I'm on as red as red can be for example), and it's definitely not white despite having a hex value of 'ffffff'. More of a horrid littler girl barbie princess plastic pink.
I imported a white square as a new sticker, used that as the base layer above the background, and it was white, but would only change along a grey scale.
Looking again at the tutorial to be sure, and this issue isn't addressed there. It's a great tutorial, but there are CAP users here making a solid first layer color changeable, and I'd love to know the trick.
Thanks and *hugz!*
