just a curiosity:
I did not notice it before (maybe because I see the elemantal chest very rarely).
It seems to be already announced at the end of the previus “normal chest”.
After receiving the “normal chest reward”, the first chest becomes “a little grey”.
After the 12H I had the green elemental chest.
I only saw it on my last chest too. I might have missed it before, but judging by the reactions here I too think it’s a very recent change.
It makes sense though - it’s now a big temptation to open the new chest with gems… just to see what’s inside.
The bottom are the gray nuances, the top are in what they’ll turn into:
There’s no discernible difference between the gray variants of purple and blue. Darkest gray will be red, and the really pale gray will be yellow. Green will be a bit darker than yellow.
Useful. Purple does look a little darker than blue to me on the chart, but that could easily be an optical illusion from the eye’s reaction to the colors to each side. If I have time later I might check that with a graphics program for curiosity’s sake.
