After Dark: Blue August 4, 2011

From azure skies to the royal use of indigo blue - spend an evening exploring the science and moods of the color blue. Luxuriate in feeling blue, grooving to local blues musicians. Watch dye demonstrations, from tie-dye to henna or find out why the sky or the water are blue and much more. After Dark is for adults 18 years and older, and is included in the price of admission to the Exploratorium.
