The color is natural, at least as natural as when shot though a
wrapper cut and held over the lens with a rubber band and used as poor man's solar filter. It was amazing how well the cheap wrapper that you typically would just toss in the trash made for a perfect solar filter. I think it also added a bit of refraction of the light causing the rainbow like color in the sun.
The next Solar Eclipse will be on August 20th, 2017. Just a mere 5 years beween the two eclipses. The 2017 eclipse will be a Total Eclipse as it crosses diagonally across from the Columbia River to the state of Georgia. Depending on your location is will be a partial eclipse as show here or as a Total Eclipse if your in the right spot. I intend to be in the right spot for the Total Eclipse.
