From yesterday:
I would call the glass teal. It's a blue-green. It's actually pretty close to a color used in some of the renders, especially the night pics, if I remember correctly. Looking at it next to 500 w 2nd which is almost a royal blue, you get quite a lot of contrast and the greenish hue pops.
I would actually say the closest color we have downtown is the glass on the new UT building. I've always seen it as a blue-green, and even just green in darker lighting. Third and shoal seems to be a few shades lighter than that.
