It is shown that a relation exists between the period and the area of the closed counter-clockwise path described in a two-colour diagram by an RR Lyrae star. Moreover, this area may be correlated with the work per cycle per gram performed by the photospheric layer of the pulsating star. The anomalous behaviour of RU Psc is pointed out.
