The hue isn't changing, you're just intelligently inserting different kinds of colors! Unless you can refer to the exact point at which a color "changes" then clearly colors are perfectly designed by God to stay within their own kind. I mean, do you have any idea how confusing it would be to determine the color of the sky if it kept randomly changing every single day as you silly atheists believe? In order to prove that colors change you would have to prove that the sky isn't blue!
P.S. If blue comes from red, how come we still have red?
