The question is ambiguous. I assume it is asking what the actual shoe colour is, not what colour it appears to be in the photo, which are the colours Brian has extracted with Gimp. I did some white balancing, with the assumption that the laces are white. I think the actual shoe is pink, but it looks teal in the photo owing to distorted colour balancing. Here is my result, The hand is now more flesh-coloured and the wood of the Alvar Aalto table looks more natural.
It looks that way to me too. But it isn't, as I determined with my color picker in my previous post. As Hermes notes, the question itself is ambiguous.
It is said that "an artist is some who wonders what the color of a glass of milk in the shade is." When we see things in unfamiliar or unusual lighting conditions, it messes with our heads, because the lighting will change the color of the light that hits our retinas, but our brains will want to work out what color the object "really" is. But of course, in a very real way, there ain't no such thing as the "real" color. What you see is what you get. It may be that the shoe's "real" color is actually pink and white. But that's not the color that's issuing from the screen!
