What characteristic of stellar emission prevents us from seeing pure colors like green or purple?

Answer

Stars emit light across a broad, continuous spectrum.

Because stars emit energy across a broad spectrum, the eye integrates the input from adjacent wavelengths. For instance, a star peaking in green still emits enough light in other regions to look white or yellowish, rather than purely green.
