====Colour====

A colour is given as a set of four numbers, separated by commas. 

The numbers are decimal between 0 and 1, each representing one colour of the RGB colour space, plus an 'alpha' (transparency) factor.

Here are some common values...

^RGBA Code^Colour^
|1,1,1,1|Solid White|
|0,0,0,1|Solid White|
|1,0,0,1|Solid Red|
|0,1,0,1|Solid Green|
|0,0,1,1|Solid Blue|
|0.5,0.5,0.5,0.5|Translucent Gray|
|1,1,0,1|Solid Yellow|
|0,1,1,1|Solid Cyan|
|1,0,1,1|Solid Magenta|

Note that many effects will ignore the transparency factor.
