+This "API" serves a global table that allows you to refer to colors by their name, instead of their associated ID/number. The table serves as a look-up in both directions, so for example `colors.blue` has the value `11`, whereas `colors[11]` has the string value `blue`. These are the defined colors:
+
+- White (`white`), Number: 0
+- Orange (`orange`), Number: 1
+- Magenta (`magenta`), Number: 2
+- Light Blue (`lightblue`), Number: 3
+- Yellow (`yellow`), Number: 4
+- Lime (`lime`), Number: 5
+- Pink (`pink`), Number: 6
+- Gray (`gray`), Number: 7
+- Silver (`silver`), Number: 8
+- Cyan (`cyan`), Number: 9
+- Purple (`purple`), Number: 10
+- Blue (`blue`), Number: 11
+- Brown (`brown`), Number: 12
+- Green (`green`), Number: 13
+- Red (`red`), Number: 14
+- Black (`black`), Number: 15
+
+Note that the indexing starts at zero, not one.
