Can you see it?  I can't.

I made a pink question mark in an increasingly dense field of gray circles. I modeled it off of a colorblind test I took online, trying to find colors I had trouble with. To me, originally the gray colors looked closer to green, but as it turned out they weren't. I used an eye-drop tool to make sure I got it just right.

To make this, I started with the question-mark. To make it easier on myself, I started out with the question mark being light blue, so I could differentiate while I was making the picture, then filled it in later. My friends also helped me as I got more confused.
