They all emit their light through thermal radiation over all parts of the electromagnetic spectrum, meaning they all have black body emission that is continuous and can never be of pure green color.

Stellar spectral classification utilizes seven main classes (O, B, A, F, G, K, M), ordered by decreasing surface temperature, with each class further subdivided into numerical subclasses (0-9) ...
