Hint 2

Colors have names

NINETEEN COLORED DICE

How we get this:

Take the color of every colored dice (white, orange, red, black, green), and index into it by the number on the dice. If the number is invalid (indexing 6 into white, for example), then the result is undefined (using _ as a placeholder). The result we get is:

 w_ignore
nineteen
colo_red
_dwiwc_e

Taking the top line as a command (ignore 'w's), and removing it from the output, this changes into the following:
 nineteen
colo_red
_d i c_e

So, the answer is "nineteen colored dice". This makes sense because (looking at the image) there are 19 colored dice, and 13 white dice.
