Is it possible for two components of a dye mixture to have the same Rf values for a given solvent system but have different colors?

I need to know this for a lab question, but I'm not entirely sure what it is asking or how to answer it. I know what Rf value is, but not what the question means. The lab used markers and dyes, if that helps any. Thanks.

Now, before you start to lecture that I need to do my own homework, know this: this is out of my own curiousity! I took physics in high school, but the college I'm attending doesn't offer physics courses, so I'm left in the dark of some of the more advanced topics. I love to learn, and am fascinated by physics, and this topic has always intrigued me! I'd appreciated only serious answers.

I hope too many people weren't out last night trying to look for it. What a joke that was, with a million victims worldwide. Just shows how crap information can be spread all over the world almost instantly with the internet.

Don't believe all you read, folks, without applying your own thought or checking up in good literature.
