I appear to have a problem with windows in the switch bar flashing when halting the default TEXT via:

^*:TEXT:*:#:

When using haltdef, it halts the default output, but stops windows from lighting up a specified set color from the mIRC options dialog. Is there a possible way around this, or some sort of command to set the switchbar channel color?

Like: /tcolor # 3 - to set the text for a channel on the switchbar to green.

You could try:

/window -gN @window

Where N is:
0 = no color
1 = message color
2 = hilight color
