Colors are not as bright as they appear

A photo where hospital scrub green appears spring green.
Tricks

So I have this shirt, and it’s “hospital scrubs green”, but when photographed at close quarters with my phone, it looks more like a bright, spring green. Light does funny things to colors, as people who have seen The Dress might be aware. I had an architect tell us once that with one can of paint, he could use different lighting to give every room a different color. At the time, I did not believe. Now with the dress, I believe it is possible. (Just not that the architect in question pulled it off.)
