This is my first time askin on Cog Sci board, not sure this is a right place to ask but I think it's something relates to Psychology and Cognitive Science.
So yesterday I bought a shirt that looked very nice on my with its grayish color. I brought it back home and tried it again but I was surprised that the color was not as grayish as I had seen in the store, but rather bluish. Thought I picked up the wrong one so I asked my roommate but he said that it had happened to him once before that the color didn't turn out to be exactly the same as he had seen in store.
I'm interested in that phenomena but don't really have enough knowledge in that field to search for a right term or word. So can you please explain that phenomena in short and which field/term should I dig into in order to explore it more?
