I'm trying to change the color of the following theme:

Examen Profesional ITAM

I can change the color with the \usecolortheme{} command, but I specifically wanted to change it to green (#009045) because it's my school's color.

Basically I wanted the theme to follow the same style, just change the green color that is currently already present to the color #009045

This beamer theme ZMBZFMK, which is defined in a file called beamerthemeZMBZFMK.sty, uses a specific \colortheme that is loaded using the file beamercolorthemeZMBZFMK.sty. And this files defines the green color used for the boxes and headlines on the frames with \definecolor{tublue}{RGB}{0,152,103}.

Thus, you may want to redefine this color directly after having loaded this beamer theme. So, in your preamble, look for the following line:


and add this line after it (which overrides the default definition of the color tublue which is actually the green you want to change):

\definecolor{tublue}{RGB}{0,144,69} % decimal representation of #009045

Note that this will not change the color of the logo, for obvious reasons.
