We discuss ongoing efforts to use the remarkably simple linear evolution of Type Ia Supernovae on color-magnitude diagrams to improve their utility as standard candles. This method is known as CMAGIC, and we describe what information can be extracted from these fits using low redshift SNe Ia. At high redshift we demonstrate that the CMAGIC relations hold for well observed objects and that current data sets can be used to cross-check previous cosmological results. Finally, we show that SNAP will excel at such measurements.
