Honestly the ECRU Dye on Rit's site looked white on their site. But I checked a color chart and apparently its a lightish yellow? Odd thinking that the color of the image would be wrong on their own site. Either way, I'm going to stop by a crafts store and find a paint that works if that is the case. If all else fails we'll have another black success story.
EDIT:
This is the dye I was talking about.
http://www.ritdye.com/Powders.28.51.6.31.lasso It looks white or at least like a light gray on their site. But oddly enough their own color chart says that it is a yellow. I'm either going to find a white paint that works, or try making the back cover this color dark blue ...
