Quote: Colors Are Relevant To The Colors That Surround Them

"Nothing in nature is actually the colour that we see it. It only appears to us at a given moment as a particular colour in relation to other apparent colours which surround it. Thus we may walk out on a rainy evening when the sky and everything is grey, and come indoors and light the lamp, and immediately the sky which we see through the window appears as a beautiful and tender blue, though there was no trace of blue in the sky a minute before, when we were outside. The change is produced in our senses by the colour of the sky taking its place in relation to a range of warm colours in the lighted room. In the same way the presence of a man with a lantern, or a light in a window, will apparently change the colour of things in its neighbourhood, and a mass of any strong colour, such as red, blue, or orange, will suggest its complementary colour in surrounding objects."
