Color exists every time we open our eyes in our consciousness, which brings up an interesting point.  People use words to name the colors they see, and use coding values RGB/CMYK to explore the truth of colors. However, when you look up to the sky, is a single blue convincing enough to describe the blue that fades toward the skyline? The sky is acted upon by human subjective experience, providing people with a blue experience. As Stephen E(1999) said that the color could be treated as an adverb rather than an adjective, like: I eat in a hurry, walk in disregard of manners, and "bluely" see the sky! So, what is the real color? In this project, colors from objective physical attributes are hidden, and those colors that cannot be described in subjective consciousness will be explored and studied.
