The objective of this study was to determine the difference in color development between exposed and shaded fruit of `Loring' and `Raritan Rose' peach (Prunus persica L. Batsch). Chromaticity values (L* a* b*) were measured with a Minolta CR-200b colorimeter on 10 tagged fruit on each of 3 trees of each cultivar. Five fruit were fully exposed to sunlight and 5 were shaded. Measurements were made on each fruit from July 17, 1991 through harvest. Differences in the a*/b* ratio between shaded and exposed fruit were observed at the first sampling date and increased towards maturation; shaded fruit approached a*/b* values similar to exposed fruit at a significantly later time. Shading reduced relative fruit color development more in `Loring' than in `Raritan Rose'.
