Counting colors

Counting colors

If you look at the figure you will see three groups of stripes one with gray tones, another with blue tones and the other with red tones.

How many different shades of gray, red and blue can you count?

Solution

If you look closely you will see that there is a single gray tone, one blue and one red although it seems that there are two shades of each. If in doubt, you can open the drawing with an image editor and check the color of each area.
