Hello, I am not entirely sure what you mean by blue color appearing. I am guessing you mean this http://en.wikipedia.org/wiki/Blue_screen_of_death. Also I do not really know what you mean by "turn off some of the operating system". The operating system is necessary to run the computer so you can't really "turn it off". Did you delete, accidentally or intentionally, any files in your Windows folder? Perhaps some files are corrupt, or you have a virus or malware or your hard drive is worn out. Hard to really say without more information but maybe that gives you some starting points for finding an answer?
purpleish
It's not. Linux does not even HAVE a color. It's just a kernel. Distributions built on top of it can have any wallpaper they choose.
Blue White
they appear blue due to the flame
green
they do not, the sky is a blue color because that is the color of light that breaks through the atmosphere. if air molecules did make the sky appear blue, then how would you explain a sunset?
Everything obsorbs or bounces light off of itself. There are also many wavelengths and different types of light around us. This blue object obsorbs each and every color except the blue you are seeing. The blue light reflects off of the object, thus making it appear blue to your eyes.
will appear black
Blue is blue because things that are blue actually repel the frequency of light from the sun that would appear blue. Because that is the only color light that is reflected, that is the only color that we see. Things that are blue are actually every color BUT blue!
