Color is a large part of our lives, though we usually overlook it. In the emotional range,
from "seeing red" to "feeling blue", color is everywhere. If you were inclined toward puns, you might say it "colors our experience".
from "seeing red" to "feeling blue", color is everywhere. If you were inclined toward puns, you might say it "colors our experience".
But have you ever wondered where all the colors we see come from?
Our
inspiration is found in the gorgeous hues of the natural world: the
yellow of a daffodil, the blue of a clear sky, the red of a ruby. But
when it comes to manufactured goods, all those shades and tints must
come from somewhere.
Let's take paint for example. Generally, paint has four components:
- Pigment – provides color
- Resin – holds pigment particles together, helps adhere to the painted surface
- Solvent – in which you dissolve the pigment and resin
- Additives – various optional ingredients to improve qualities of the paint
So where do the pigment particles come from? Does some chemist wave a magic wand and produce Orange Umber?
The
answer is more down to earth. Some paint pigments are made from plant
sources, some from mineral sources. Because plant-based pigments aren't
as durable, most industrial paint today is made from minerals.
Here are some of the sources for these prime pigment colors:
Titanium Dioxide – White
Iron Oxide – Yellow, Brown, Red or Orange
Chromium Oxide – Green
Cobalt Oxide – Blue
Carbon – Black
Titanium Dioxide – White
Iron Oxide – Yellow, Brown, Red or Orange
Chromium Oxide – Green
Cobalt Oxide – Blue
Carbon – Black
Of
course if you want to make very special paint – as has been done in
many cultures down through history – you could grind the pigment from
semi-precious stones like turquoise, jade or lapis lazuli!
