Look at this picture. How many colors do you see?
Do you really see a blue stripe? Well, there is no blue color at all in this image ...
Actually, what you think to be blue is a green color in truth.
If you don’t believe it, you can zoom the blue stripe in Photoshop. I did it but in Paint.
Our vision is misleading sometimes ;)
