Comment (by Paul K. Gerke):
Hi, I am, of course, happy to explain!
> When using the current circle shape, are you able to distinguish between
"yes" and "no" using the "checkmark" and "X" symbols inside the circle?
> And when changing only the shape from circle to square, what specific
difference makes it easier to distinguish between the two?
For me, as for others affected, the contrast ratio between green and red
is very muted. A coarse test, that is valid for all color viewing
deficiencies, is to simply convert the image to grayscale. For your
convenience:

grayscale.png
As you can see, the brightness and shape of the symbol remains, but both
are relatively similar:
- The gray tones are close, different but too close for skimming
- Both symbols, are essential "a round thing with something white inside"
The ideal solution would be one that takes both these properties to and
exaggerates their differences. That is how I can to the suggestion to
change the shape between the two symbols. I imagine that changing the
outer shape of one of the symbols to a rectangle will make that symbol
cover more area and therefore it appears darker (more dark pixels in
total), and secondly it the outer shape of the symbol also is changed so
that one now can distinguish rect/round as well. (I also read somewhere
that people with viewing deficiencies are seemingly more trained to
recognize shapes than color, but that is only half-knowledge of mine).
Since I had GIMP open already, here a coarse simulation of what that would
look like:

@Srinjoyee_Dey - If we all agree on the issue/solution, you are more than
welcome to take it out of my hands, if you want!
