Blue spots on purpurea

[Shiftyfrank]

So one of my pitchers has started to develop a bit of a bluish rash looking thing, its one that was sunburned a bit already when we bought it. I've been unable to find any one else that's asked about blue spots on a search. Here's a photo:

Something I should be worried about? I also just noticed the other pitcher that arrived burnt also has some, is it possible its related to whatever damaged them initially?

Looks good to me. I don't see any blue. The red is from light exposure- and if anything this plant may appreciate more sun. How many hours a day of full sun does it get?

 

[Shiftyfrank]

I'd say about 8-10 hours of direct light if its sunny and 15 or 16 total. Its just a few spots and in the last little while they've started to turn white

Also, this pitcher in particular arrived damaged (it was a bubble of death rescue) and some of the stronger pitchers have colored up nicely. I definitely haven't noticed any new burning, and probably came from when the plastic intensified the sun. Our brand new leaf came in strong as an ox and bright green. Here's a more recent photo of the whole thing
