These look the same
A few weeks ago in Vegas, I saw the glass flowers at the Bellagio. I walked by, but then came back to take a couple of photos, because as I thought of it I realized that the glass colors really looked a lot like my number-colors. (On a side note, I just read that synesthetes often have trouble representing their perceived colors with paint because they're thought of as colored light rather than colored pigment. SO TRUE. Though obviously there are ways around this. But, I think this is why the colored glass was so compelling--it's much closer to light than pigment.)
