We have used the infrared flux method (IRFM)
temperatures of a large sample of late type dwarfs given by Alonso
et al. ([CITE]) to calibrate empirically the relations
(colour, [Fe/H]) for the Vilnius, Geneva,
(Cousins) and DDO photometric systems.
The resulting temperature scale and intrinsic colour-colour
diagrams for these systems are also obtained. From this scale, the
solar colours are derived and compared with those of the solar
twin 18 Sco. Since our work is based on the same Teff and
[Fe/H] values used by Alonso et al. ([CITE]) to
calibrate other colours, we now have an homogeneous calibration
for a large set of photometric systems.
