Rest‐frame B−V colors vs. redshift. Red circles are primary early types, and blue circles are secondary early types. The squares are all other galaxies in the ﹩H_{160}< 24.0﹩ sample. Filled symbols have spectroscopic redshifts and open symbols have photometric redshifts only. The horizontal dashed lines are the colors of CWW spectral templates. The curves represent the colors of Bruzual & Charlot models described in the text. The solid red curves represent a 0.1 Gyr burst that starts at ﹩z_{f}=5﹩, 3, and 2.1 followed by passive luminosity evolution. The magenta dot‐dashed line is a ﹩\tau =1﹩ Gyr exponential model with ﹩z_{f}=2.5﹩, and the two blue, long‐dashed lines are ﹩\tau =5﹩ Gyr exponential models with ﹩z_{f}=1.5﹩ and ﹩z_{f}=5﹩.
