Solution

There are 3 yellow-blue balls located in C2, H3, and E6 (<- highlight with the mouse). In visual perception, search is very difficult when you have to find an object with a combination of two SAME attributes (colors), than with more complex attributes (color + form). Lisa Chavis answered: NONE! Anton Sparks answered: 0? - On further reflection - at least 3? Sherri Sells answered: There are no yellow and blue balls, only red and yellow and red and blue balls. Irene Hoogmoed answered: 0! Cynthia Henderson answered: Zero yellow and blue balls. You're encouraged to expand and/or improve this article. Send your comments, feedback or suggestions to Gianni A.
