In order to accurately map the formation and evolution of galaxies, it is essential to assemble complete samples of galaxies over a wide range of redshifts. Galaxies at the highest redshifts (z>2) are currently selected by virtue of their colors falling within specific regions of color-color diagrams. These regions have been confirmed spectroscopically to contain high redshift galaxies at high reliability. However, the fraction of high redshift objects contained in these regions, i.e. the selection completeness, is less well defined. Even for a single galaxy spectral energy distribution (SED), variations in the intervening absorption between different lines of sight create a distribution of possible colors, some of which may fall outside the selected region of color-color diagrams and be overlooked. To quantify the completeness of high-redshift galaxy selection via colors, we model galaxy colors from 1.75
