I came across a listing of this set on another site that I can’t link here, and
those 2x4 plates are definitely not Light Blue. The bag in the listing is still
sealed and maybe an inventory admin can come to their own conclusion on what
this color is? If need be, I can still provide said link through a different
means.
[...] I tend to say it is bright light blue. I also found a second listing which shows the build set. I will see if I can find out more about this. (31 months ago, Oct 24, 2021, to Catalog Requests)
