Below is a picture and a set of numbers. There are 6 question marks. Try replace them!
I think the answer is
First convert the binary numbers to decimal:
$64, 43, 36, 54,$ ????
Now, notice that there are five numbers and five shapes in the picture. Therefore, it's seems reasonable to guess that each number corresponds to a shape. With a little bit of thought I found that the first digit in each case corresponds to the number of letters in the colour of the shape and the second digit corresponds to the number of sides. Specifically, the correspondence is as follows:
$ 64 \leftrightarrow$ YELLOW, 4 sides (diamond)
$ 43 \leftrightarrow$ BLUE, 3 sides (triangle)
$ 36 \leftrightarrow$ RED, 6 sides (hexagon)
$ 54 \leftrightarrow$ BLACK, 4 sides (rectangle)
The only shape so far not included is the GREEN pentagon which would correspond to $55$ or $110111$, in binary.
