Here's a Scarce Sky Blue CD 154 Vidrart mold#31 (left in the photo). Color is very close to a Sky Blue McLaughlin. Photo seems to show a sage blue tone but it is in fact a true Sky Blue- which is different than a Powder Blue as there are no Cornflower influences in it. As you can see it contrasts nicely with the killer Cornflower Blue (right in the photo) next to it.

The Sky Blue has an inner skirt chip and reverse skirt nick/ping (1/2 pinky nail size) and about 16 scattered tiny tic marks, otherwise excellent condition.
