3D-LCD technology is beginning to become popular in video entertainment display devices. For ultimate viewing experience it appears attractive to better understand the influence of color within 3D scenery with regard to visual perception of shape and depth. To facilitate such a task, 3D graphics renderers offer a suitable experimental approach. Enabling comparison of simple synthetic scenarios when combining 3D-modeling and color component synthesis one can also extend it to naturally looking scenarios. Consequently, relevant color parameter modifications carried out successively and independently may lead to optimal discrimination of their influence. Taking into account mathematical color mapping techniques that are based on mapping 3-dimensional color space into monochromatic space we address valuable findings such as subtle blue shifts in aerial perspective (due to light scattering) often reported by artists as important visual cues. After searching for counter-proofs that efficiently define contradiction associated with each parameter one can predict influence of color in relative quantities with regard to depth cues. Further experiments focus on color dependent depth perception of an object moving within synthetic or natural scenarios. Applying synthetic objects in such scenarios we searched for visually perceived depth locations as a function of object color. Subsequently, a comparison of color dependent depth perception between static objects and motion objects is also discussed.
