Able To Use SM_ Commands In Maps?

As i've been developing a map i have been wondering if i were to be able to use sm_ commands in maps for ie. football using sm_colour.

 

I think you can learn a lot from decompiling other maps and looking through them. I know that you can implement "@say Map by Jan" as a trigger command. But to colour players, you can look at this: https://gamebanana.com/tuts/6808. I know that jb_sunshine by trig has colour changer box.
