Chemical and Photometric Evolution Models for Disk, Irregular, and Low Mass Galaxies
Color-color diagrams. Colors - versus -, - versus -, - versus -, - versus -, - versus -, and - versus - are represented as blue dots and compared with observational data. The standard values for typical galaxies along the Hubble sequence as Sa, Sb, Sc, and Sd are taken from Poggianti  and shown as in magenta letters. In the panel - versus -, the yellow line corresponds to data from Vitores et al. , the red dots are from Buta and Williams (, BW95) in - versus -, from Peletier and Balcells (, PEL96) in panel - versus -, and from de Jong (, dJvK96) in - versus - and - versus - panels The green full squares are from .
