Here's a set of macros that I've been working on for a while, and 
finally feel like I can submit. It effectively allows you to place 
standard theatrical instruments in your scene, and attach various 
accessories (colors, template patterns, etc).
I tried to make everything in here as realistic as possible, in terms of 
photometric data, and left a lot of room for modification and expansion. 
It uses LightSysIV (and CIE.inc) from Jaime for color and fading 
calculations.

Color filters (Gels in the technical lingo) were modeled by taking the 
transmission spectra for each color in spline form and passing it 
through CIE to create colors as accurately as possible. The lamps 
themselves use the rated blackbody temperatures of the real lamps, so 
anything made in this should look nearly identical to what it looks like 
in person, within gamma and monitor calibration tolerances.

The zip file contains a folder that contains the main include file, a 
sample proscenium theatre space to test lights in, a wooden stick figure 
to test with, transmission spectrum data for 3 major manufacturers of 
gels, a fairly detailed readme with usage instructions, and a few demo 
scenes to try.

Let me know what you think!
