It was never white.
It was one of the off-white shades. Whiter than beige but it still had some creaminess in it so a little more like ivory.
Exactly. Pictures are difficult to go by due to lighting and camera/monitor calibration variances.
From what I can tell over the years, the Escom cases I've seen appear to have been newly manufactured, and the color is a tad whiter than the earlier C= cases. Nothing extreme, but side-by-side, you can tell the difference between the two easily.
