Document Summary
We create things in the mind that we enjoy. Can look at colours when go through prism. If add all colours of light together, then the light will be brighter. Colour is difficult to see in some ways. Colour is so(cid:373)ethi(cid:374)g (cid:449)e per(cid:272)ei(cid:448)e. it does(cid:374)"t a(cid:272)tuall(cid:455) e(cid:454)ist. We (cid:272)a(cid:374) see (cid:373)illio(cid:374)s of (cid:272)olours that do(cid:374)"t e(cid:454)ist. Colour perception helps us to distinguish things in complicated environments.

If superimpose all these, then get the original image. Neurons are important in certain types of features and aspects of colours. Green filter: nose and stars (and some parts of the hair) appear equally bright but actually are very different in colour. A lot of green light from the cheeks. Seems as though the star and nose have the same luminance.
