Like if you play chess for hours and hours every day, eventually you start to experience everything in terms of chess moves. It's the same with color. Look at just about any flat surface long enough and you'll notice it has a hue, saturation and value. Just go into Photoshop and you'll see that boring white wall has variations in hue, saturation and value, it's no medical mystery in my opinion.
This part is a tiny more green, that part is a tiny more blue. I'm not giving you an art lesson here but you get the idea. Artists know they can make things look farther away by painting them blue/gray, decrease saturation with distance, etc. The painter learns to exaggerate because she just has a 2D surface to work with. Anyway, through the process of painting our perception of color improves, even when we're not painting.
K-12 the goal is just paint the sky blue and the grass green, color inside the lines and get your grade. But if you want to be a serious painter at some point, you may want to look at things fresh, more intently. When people see your paintings, don't expect them to care how long it took to mix the color. Only a few artists will notice and they're not the ones buying your work.
So even for artists, seeing color is not terribly useful, because mixing color is very time-consuming. It's more a hindrance than anything because I can finish an ink wash in 1/100th the time and sell that for the same price as an oil painting of the same subject.
If you have all the time in the world and don't need money, I say go for it, buy some expensive oil paint and send me an email, I'll tell you what to buy. Stretch the canvas yourself and go all out.
