Ainda não se sabe por que faltam à luz do Sol algumas cores. Aqui estão todas as cores visíveis do Sol, produzidas pela passagem da luz solar através de um dispositivo semelhante a um prisma.
Os retalhos escuros no espectro acima provêm de gases na superfície do Sol, ou acima dela, absorvendo luz solar emitida abaixo. Como diferentes tipos de gás absorvem diferentes cores de luz, é possível determinar quais gases compõem o Sol.O Hélio,por exemplo, foi descoberto em 1870, em um espectro solar, e somente mais tarde encontrado aqui na Terra. Hoje em dia, a maioria das linhas de absorção espectral já foi identificada — mas não todas.

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 does indeed appear brightest in yellow-green light.
The dark patches in the above 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 1870 on a solar spectrum and only later found here on Earth. Today, the majority of spectral absorption lines have been identified - but not all.
