Grey became Medium Stone Gray, Dark Grey became Dark Stone Grey… but did you know that Lego changed all these other colors at the same time?
The two Modulex bricks are just placeholders, representing 211 Turquoise and 223 Light Pink. As far as I know, those colors weren’t used in sets. I haven’t been able to compare these Mx colors in person yet to see how close they are.
