The so-called ‘weak helium’ stars are discussed from a spectral classification point of view. Several authors have included different kinds of objects in this class. Often, the only similarity is the discrepancy between the spectra and the colours. It is desirable to decouple the discovery of new members of the class from this dependence on colours so that the colour can be used as an independent parameter.
