The shadowing around this "colour" implies more than texture, it adds a sense of separation between it and the page. Paint of a certain colour, once on a page, belongs to it while this one almost has a sense of individuality. In this case however, it gives the impression that this 4th dimension adds an energy component making this perhaps more of an idea than a colour...You have created the first tangible idea...only it's still imprisonned inside your work.

A tetrachromat is an organism for which the perceptual effect of any arbitrarily chosen light from its visible spectrum can be matched by a mixture of no more than four different pure spectral lights.
Tetrachromacy has not yet been demonstrated as a characteristic property of any mammalian species, though it is likely that it occurs in some birds, fish, amphibians, reptiles and insects. Humans and other Old World primates normally have three types of cone cells and are therefore trichromats. However, at low light intensities the rod cells may contribute to colour vision, giving a small region of tetrachromacy in the colour space. It has also been suggested that women who are carriers for certain kinds of color blindness (protanomaly or deuteranomaly) may be born as full tetrachromats, having four different simultaneously functioning kinds of cones.
So at low light levels we can all see the fourth primary colour, using our rods as colour sensors.

Well next time in a dark room I'll pay extremely close attention to the colours I see - maybe a fourth one will appear. I'm closing my eyes tight right now, and all I'm seeing is black, and some purple.
You mentioned one deficiency - deuteranomaly. The picture below shows what its like to have this deficiency, versus being a normal trichromat.

Wonder what this picture would look like if it compared a normal trichromat to a tetrachromat?

I did some reading on Becker, fascinating work - thanks for the comment.
A picture of Ernest Becker, from this website.
From the bits I read on the net, Becker believed that we humans create fantasies about our own physical limitations, mainly death, in order to give us the strength to continue living. These fantasies allow us to ignore the fact that we will one day die, and that we don't entirely know what will happen after.
Which brings up the question - why bother learning what your weaknesses are? Why not convince yourself that your imagination is unlimited, or believe that good things will happen after you die? At least this gives you hope and happiness.
