Yes - it's the light frequencies that let us differentiate colors, but we're not always going to perceive the same color each time our frequency detectors (cones) detect the same frequencies, since color perception is more about the whole scene and what we're experienced before.
Another simple experiment that proves this is when you put on color tinted sunglasses or ski goggles - initially everything will seem color tinted, then after a while colors go back to normal.
It's not just color - the whole idea that our eye works kind of like a camera and what we see is what is is really there is wrong. There have also been experiments done with prism-based inverting goggles that make everything look upside down... It turns out that after you've worn them for a while then everything flips the right way back up again and looks normal to you, even though the googles didn't change.
