Controversy is raging over the question which of the relations linking periods, luminosities and colours of classical cepheids should be used to the greater advantage of cosmologists in desperate need of a reliableprimary distance indicator. Adopting a cepheid evolutionary scenario of utmost simplicity, Sandage and Tammann (1969) (=ST) have introduced the concept of an universal period-luminosity-colour (PLC) relation which is expected to minimize the Malmquist bias by virtue of its small intrinsic spread; the PLC relation constitutes the only primary pillar of their controversial distance scale. More recently, Stift (1982) and Clube and Dawe (1983) have shown that there are good reasons to consider a more realistic and hence more complex picture of cepheid evolution and photometric behaviour.
