Multicolor CCD observations of red stars have been made over the past fifteen years with different telescopes, filters and camera systems. The purpose of this study was to develop a more efficient way of putting all the data onto the same standard photometric system. A calcium hydride filter was also used as a discriminator between red giants and red dwarfs, and standard values for the R-L (CaH) color index were calculated. A brief description of the different transformation methods is provided, focusing on transforming data from the U55 (R-L) system to the U42a system. Results from each system were compared to ensure the accuracy of these methods. Values from the U55 system proved to be essentially the same as those for the U42a system.
