> As neuroscience advances, what is the likelihood of truly novel color experiences?
No need for neurosciences, just some fancy spectral filters like those on IMAX 3D glasses. With some practice using these glasses you can experience a six-dimensional color space. When you remove your glasses, this six-dimensional space collapses into the common three-dimensional color space. But with the glasses, you can distinguish many different colors that look exactly the same to regular humans. That white wall? It looks a perfectly uniform white to most people, but you can see clearly that two very different kinds of white have been used here and there.
A similar effect can be obtained indoors by lighting objects with monochromatic lights, but it is not as dramatic as with glasses.

I used to work in highway paving, and I learned how to tell the temp of asphalt with polarized sunglasses. It's not the same as a truly novel color experience but its a neat party trick
