The color of a cataract

Wolf had the first of two cataract surgeries last week.  After 5 days, the eye on which the operation was done can see well enough to use the computer, so he's back at work.

He has been in wonder at the change in colors.  The cataract caused a yellow shift.  He used one of the drawing apps to show me the color difference between his eyes now (with only one of them still having a cataract) and it's remarkable.  I remember when we disagreed about the color of something.... I said it was a shade of blue and he said it was green.  Now we know why!
 
This is what white looks like in each eye now.

Amazing!
