Look at this image:
The two labelled squares are actually the same colour.
This shows that context is very important in deciding colour. The tent in the picture might actually be a colour that I would call pink in a different context. But since the context is that light is hitting it, and it's thin and therefore slightly transparent, I call it red.
i have checked the shade of grey that those 2 squares are and they are the same shade of grey (they are not a color)
it is very interesting that the checkerboard pattern must have gone out of kilter somewhere for the "b" square to be the same shade as the "a" square. the checkerboard pattern seems to be uninterrupted, but if "b" is the same shade as "a" then i can not see where the pattern went out of sequence.
anyway, i wrote a simple program that i use to understand colors, and i think that the color of the tent is 220/255 red, and 40/255 green and 90/255 blue (all combined). it is not exact, but in my mind it is close. i conceived of the true color (in my mind) without exceptional illumination.
