The relative preference for six different reticle colors was determined under three conditions 1 high level, varying luminance, 2 low level, varying luminance, and 3 high level, equal luminance. All colors in each condition were presented by the method of paired comparisons. The results indicated that in the first two conditions, green, orange, and yellow were almost equally preferred. In the third condition, green was most preferred. Background was not a significant factor in reticle color preference.
