Yes.
ambiencered=x
ambiencegreen=x
ambienceblue=x
Unlike the ambience with its max value of 100;
the ambiencered, ambiencegreen, and ambienceblue have max values of 255.
The light's color can be any color in the RGB triplet.
For instance..
:state=0:ambiencered=255,ambiencegreen=0,ambienceblue=0,state=1
Would set the color to Red, because we set red to its highest value and the others to zero.
If you want Green then we would use...
:state=0:ambiencered=0,ambiencegreen=255,ambienceblue=0,state=1
If you want Blue then, yep you guessed it...
:state=0:ambiencered=0,ambiencegreen=0,ambienceblue=255,state=1
Most paint programs tell you the RGB values of any color you pick.
This can simplify the process by getting closer matches the first try.
