Hi all-
I am trying to create stimuli for a research study and need to control for the amount of one color in a display. I am creating various-sized circles that are either red or yellow on a black background. Is there a way to count the number of pixels of one color on the screen? If I use the magic wand and the shift key, I can select all the circles of one color, but it only gives me dimensions for the bounding rectangle, right? Is there a way to do this?
THANK YOU!
