What are seven colours of white light

In kindergarten, we learn red, orange, yellow, green, blue, indigo, and violet.

But the truth is that the rainbow, or true white light, contains EVERY COLOR that the human eye can detect.

Sure, ROYGBIV is in the rainbow.  So are amber, aqua, beige, blond, canary, coral, ebony, emerald, flax, fuchsia, gold, heliotrope, ivory, jade, khaki, lemon, maroon, navy, olive, pink, rose, salmon, tan, umber, verdigris, wisteria, saffron, and millions of others ... some without names.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
