Colors can be created from four different triples of values (color-spaces): 
<color red=153 green=0 blue=255/>
<color red=200 green=50 blue=100/>
You can access a color component via its name.
<color 1 2 3/>.green2
When making a color you should usually supply all three values of the color-space. If you don't the other values will default to zero.
<color red=200/>.green0
The color class does a lot of work to make it easy to create colors in one "color-space" yet get values out of it in another color space. 
<color red_double=0.5 green_double=0.2 
           blue_double=0.4/>.saturation
152
Basic colors are defined by default: color.of.red color.of.blue Standard colors can be additionally loaded 
<resource "logical://system/data/color_f_data.h2o"/>.<execute/>
To define custom named colors: 
<color red=100 green=100 blue=0 name="my_special_color" />
color.of.my_special_color
