It depends on the lighting. Some of the shelf lighting in a Macy's near me looks like it is fluorescent and more blue. The teal might come out in more natural, yellow light. I am not fond of Macy's lighting. The light in the Coach FP store tends toward white, and natural daylight will tend to make any bag more yellow. It also changes during the day. I think morning light is more blue and afternoon light is more yellow or orange, IIRC.
So if color is a big issue, you should take note of the color of the light in the store. That was an issue for me when I ordered the nude swagger, because the color did not look that great in Macy's blue light, but I knew it would look better in yellow light since it is a more yellow color. And of course, I saw pics on tpf and the bigger version of the bag in the Coach FP store.
