Your question is based on the assumption that there is a missing hole, while there is none. Count the no. of coloured boxes, its the same, the extra box is just there because the picture is not drawn to scale. If you use real figures there ll be no blank.
There's three colours. Our mind works with association, the surrounding colours affect our perception of the colours present. A brown coloured guy wearing black clothes will appear fairer compared to the same guy wearing white clothes, a small circle in bigger circles will look smaller compared to the same circle in smaller circles etc. Theres pink, white and green colours present in the pic, in one area the pink is surrounded by dark green colours so it appears reddish, in the other its surrounded by white so it appears pinkish.
:113: Correct folks for the second one:113: but about the first picture I am yet confused and need some time to jump to a conclusion. please do care to reply my next batch of pictures.
What is the word written in the picture? View attachment 281 How many faces do you see? View attachment 282 What do you see in the image? View attachment 283
OK, hints. The black regions should be treated as entrance of igloo or cave (whatever), the nose should be treated as hand, the eye as fold at bottom of the cap and the neck as the legs. Got it.
Some Illusions When you shake your head rapidly, or better shake the display, a central disk will segregate as a distinct object, which in addition seems to be floating atop the background.
One More Illusion Here the background seems to move, while the central square remains in place, and seems to float on top.
