I was looking through some MTS themes and noticed that a lot of the colors didnt look like one of the 16 colors in mirc so I was wondering if other colors can be used and how this can be done?

i'v got your solution
open mirc
press alt+k

then on the bottom u c the collours:

right klock on one
then u c this:


then you can chouse the colout that you want , have fun ...

Cool.

One other question. I know with /color I can change things but how would I use this with colors that arent part of the 16 color palet?
I tried /color Action text 96,138,64 but I got an error saying the parameter was invalid. I am wanting this so I can have my script change it in the settings.

as far as i know you would have to define a custom color and then set it to one of the 16 color choices you can do this by opening the color dialog via the tools option at the top then right click on one of the color to open the next dialog

Oops, didn't see that /color can set RGB values too.

Ok, I finally figured it out.

To change the colors I have to use /color [00-15] rgb

Correct. /color works in 2 distinct ways, but not both at once.

//color [0-15] $rgb(N, N, N)

or

//color Action text [0-15]
