We study the internal UV-optical colors of galaxies at 1.5 < z < 3.5 using HST ACS and WFC3 images from CANDELS in the GOODS-S and HUDF fields. The internal color dispersion quantifies spatial differences in the stellar populations within a galaxy. We find that the internal color dispersion between bands that probe the rest-frame UV quantifies primarily differences in dust extinction, while internal UV-optical color dispersion constraints the amount of current star-formation to older stellar populations. We study trends in the internal color dispersion with other galactic properties such as mass, total color, and size, in order to study the relation between galaxy growth and their star formation histories. We find that for galaxies at 1.5 < z < 3.5 the internal color dispersion increases both with stellar mass and galaxy size. It remains low for low-mass galaxies and increases as the mass increases up to galaxies with stellar masses 1011 solar masses. Therefore, the process of increasing the heterogeneity of a galaxy's stellar populations (as measured by the internal color dispersion) is related to the process of galaxy build-up.
