Color fading

I'm not an expert at these things but it might help if you changed your question:Does the color of the paper effect how fast the color fades? You have color in there twice, you're being redundant.How about this "Does the texture of the paper determine the speed of color fading?" You would use several sheets of paper all of the same color but with different textures (smooth, rough etc.)and then dertermine which texture fades faster.
Or you could use the question "What color fades the fastest?" All lot of people do this so if you like being "one of a kind" you don't want to do this. for the experiment you would use several sheets of paper with the same texture but with different colors and determine the speed of fading.
I hope this helps you.
