To my deep disappointment, cosmic latte is not a super-massive coffee.
Cosmic latte is the average color of the universe, found by a team of astronomers from Johns Hopkins University. In 2002, Karl Glazebrook and Ivan Baldry determined that the average color of the universe was a greenish white, but they soon corrected their analysis in a 2003 paper in which they reported that their survey of the light from over 200,000 galaxies averaged to a slightly beigeish white.[2] The hex triplet value for cosmic latte is #FFF8E7.
