Question for Tom French concerning Scripting

First of all, thanks for responding to my Scripting question in the Halo livestream! I was thinking after the stream finished - would you be able to change the colour of some things with Scripting? So, for example, if you had a chroma screen acting as a light and it was red, could you change its colour to green, for example, when you toggle a switch or trigger, then have it turn back red when switched off?

Also, are Location and Timed Triggers still in? I want to be able to have automatic doors for some of my maps.

Tom French deserves a pay rise.
