Abstract
Simultaneous measurements for visual and visual-infrared colors provide
the means to determine both the average temperature of the giant branch
and the turnoff-temperature of the main sequence. This allows to model
fractional contributions of different populations, including age- and
metallicity-effects. The authors observed NGC 3379, 4278 and 5813 in B,
V, J, H and K. All three galaxies show significant color gradients both
in visual and visual-infrared colors, in the sense that the galaxies
become bluer going outwards.
