Abstract
The shape and color of an object in the water can look considerably differed than it would on land. In fact, the objects all-over color will appear bluish Conceming underwater optics, there are many researches in the field of the physics. How ever, research information concerning the recognition of an perception of color in the water is very limited. In this study, experiment concerning chromaticity measurement were carried out with varying the water depth and distance from the color board of white, red, green and blue Measurement results were expressed on the CIE 1931 Chromaticity Diagram. Chromaticity characteristics of different colored objects in the water were then discussed.
