The SNAP (Supernova / Acceleration Probe) primary science mission's goal is the determination of the dark energy's equation of state parameters w0 to 0.05 and w' to 0.3 using Type Ia supernovae out to redshift z=1.7. This places stringent requirements on the control of systematics and on the absolute color calibration of SNe Ia. The overall calibration for the SNAP CCD and NIR imagers and spectrograph will be conducted through several routes. We envision employing a variety of well-studied stars, certainly including the HST spectrophotometric standard stars (and possibly the Sun) and performing indirect transfer calibrations that permit comparison with NIST irradiance standards to close the loop with fundamental MKS quantities. We discuss the basic issues and possible strategies in order to achieve < 4% color errors over the wavelength range of 350 nm to 1.7 microns.
