Imagine of you will a man composed entirely of light. James Palmer is such a man. A former space explorer whose ship ventured far too closely to a black hole. James should not have been able to survive for not even light can escape the abyss that is a black hole, but survive he did though not unscathed. James underwent a transformation of cosmic proportions emerging from the other side of the wormhole as a being of pure light. he found that each wavelength of color allowed him to do different things control different aspects of reality as it were. Red, allows manipulation of heat and fire, yellow life, green positive emotions, blue death, orange healing, violet negative emotions, Infrared light is one type of light that is invisible to us. Gamma rays, X-rays, ultraviolet light, microwaves and radio waves are all visible to him, as well as being possible to manipulate. he is the ultimate stealth fighter. Using light and radiation to combat cosmic forces beyond the reach of most mortals. Illusions are the least of his powers but he can create anything he can envision as solid or ethereal light constructs. James is a good man brought up with strong values of life, goodness and responsibility. Upon discovering his newfound abilities hes has sworn to use them for the cause of Justice calling himself Prizym.
This is a cool and interesting character. I like the concept and I think you could have some fun with it. It's a good design too. I do think the chest emblem is perfectly appropriate for this character although because it's something I grew up with, I can't help but think of Pink Floyd's Dark Side of the Moon album cover when I see it.
