Details:
In a morning of August 23 the lava lake in Halemaʻumaʻu crater at Kilauea, The Big Island of Hawaii was spattering lava. Here's a video I filmed https://www.youtube.com/watch?v=PnaDejuDIq8 Notice lots of yellow colors - the color of one of the hottest lava. Later, when we went for a hike I noticed an unusually colored plume getting out of the lava lake. My first thought was "rainbow", but then I looked at the sun and it was above and to the right of the plume, not the right setting for a rainbow. The red color of this plume probably comes from the ash being ejected from the lava lake. But where the blue color comes from? I am not sure. The only things I was able to find on the NET is that the blue colors could have came from the sulfur (sulfur dioxide emission doubled in Hawaii after this new vent opened in 2008). There's a volcano in Indonesia that glows in blue colors at night http://news.nationalgeographic.com/news/2014/01/140130-kawah-ijen-blue-flame-volcanoes-sulfur-indonesia-pictures/ and Eruption on Io , one of the moons of Jupiter also has blue-colored volcanic plume http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA00293
