In this demo, at 15:04 they zoom in on the red dice. We can clearly see:
Double, Crit, Crit, Accuracy
Double, Accuracy, Hit, Hit
Crit, Blank, Hit, Accuracy
Using deduction, we know that red dice have 2 crits, 1 double, 1 accuracy, 1 blank, 2 hits, and then an undeterminable side from this close up.
Later in the video, we can see at 21:11 that there are two distinct blank sides on the red dice. So we have:
2 critical hits
2 hits
2 blanks
1 double hit
1 accuracy
