Explanation: It is still not known why the Sun's light is missing some colors. Here are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our white-appearing Sun emits light of nearly every color, it appears brightest in yellow-green light. The dark patches in the featured spectrum arise from gas at or above the Sun's surface absorbing sunlight emitted below. Since different types of gas absorb different colors of light, it is possible to determine what gasses compose the Sun. Helium, for example, was first discovered in 1868 on a solar spectrum and only later found here on Earth. Today, the majority of spectral absorption lines have been identified - but not all.

There are some colors which are unsure of their hue and are take some time off to reflect.......
The lack of some colors are due to universal racism.
They hung it upside down!
It is a distress signal.
And in sufficient quantities to use blowing up birthday balloons.
Helios is Greek for sun, right?
The only thing missing is the purple line (which connects red and violet, going through magenta), right?
There’s two things going on, right? The sun’s rays can be turned into a rainbow with a prism (missing the purple line) and also there’s the spectral analysis, no? More colors are missing from that.
Helium was discovered on the Sun first. It is named for Helios, the Greek word for Sun. The man who discovered it was given a lot of grief at first for his extraterrestrial find. Late on by crushing uranium bearing rocks tiny quantities were released . The great race to liquify Helium was often hampered by how difficult it was to obtain. Somewhat funny for an element that is the second most abundant element in the Universe.
It wasn’t practical to go to the sun to get helium—too far away.
Since there are only 118 known elements in the periodic chart, there must be more elements in the Sun that we have not yet discovered....................
They should go at night.................
Henry Moseley settled that issue. His work showed there are no in between of fractional elements. The chart had pretty much been complete since 1940. The man made stuff is usually just a handful of atoms that are gone in a fraction of a second.
On a side note, Since we can run the light from any star through a spectrometer and tell how much red shift it has by looking at a particular known element’s dark band, iron for instance, it seems to me we could use a satellite to do that and have it constantly monitor a single far distant star constantly. If the band were to suddenly move, one way or another, it would indicate that a Gravity Wave had passed between the Earth and that star. And the amount of movement would indicate the amplitude of that Gravity Wave..................
The motion is too small . LIGO detects motion as little as a thousandth the width of a proton. Einstein knew the math which is why he figured we’d never be able to detect gravity waves directly
