## Colors

### Color Names

As first defined in HTML: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, yellow

And then came 140 color names defined.

Color names OK for quick experiments, but we can do better.

### RGB Color Space

256 colors in each channel (Red, Green, Blue). Values can be

- decimal numbers (0 to 255)
- hexadecimal numbers (00 to ff)
- percentages (0 to 100%)

The following are all equivalent ways of defining a shade of orange:

rgb(100%,66%,33%) rgb(255,168,84) #ffa854 |
