The only thing I can add to his post is that you mean "affected by gravity".
You used "effect of gravity" correctly. An effect is the outcome or influence. Affect refers to what is influenced. Light is affected by the effects of a black hole.
The speed of light has never been determined in a true vacuum, we can't be sure how much light slows down due to gravity, nor can we be sure how fast light travels when gravity has little affect on it. When the speed of light was determined it was under the effect of gravity. Thus I'm saying light as a measurement of distance due to it's speed can not be considered the most reliable devise, and seeing that light is affected by gravity the color shift may not be so reliable either.
If you don't think it's a reliable method, then what is? Asking God?
