We break down the received light stectrum from a star into the individual wavelength components.
From it we claim to know its composition, heat, distance and speed. Aren't there way more unknowns that knowns?
For example, consider any arbitrary observed star with a certain color distribution. There are many possible configurations of materials which could cause that distribution (material A sucks in these wavelengths, material B sucks in these wavelengths etc.). How can you determine the quantity of each? What's more: if you consider the variables speed and heat, how can we claim to know all of these with just the emitted distribution and intensity?
Also, I am not convinced that we can determine the distribution from a mishmash of different colors. The resulting mishmash could also be the result of many different sets colors being mixed together..
