If I'm understanding you correctly, you want the switchbar color to change whenever the bot says something? If that is the case.... yes it is possible.

Open the mIRC options, go to IRC > Highlight, enter the bot's nickname, then change the text in the combo box, below where it says "Match on:", to "Nickname only".

Doing this will change the color on the switchbar to whatever color you have for 'highlight' in the display settings (mIRC Options > Display) whenever an event is triggered by the bot.
