[Terminal] Coloring (zsh)

Hi,

I've seen plenty of nicely styled desktops in unixporn, but I'm not sure how to get the same coloring in my terminal. I have started using zsh with oh-my-zsh but when applying a theme it wont look like the preview. What am doing wrong or what do I have to change.

#Env OS: Arch Linux Terminal Emulator: Termite SHELL: zsh, bash

Is oh-my-zsh able to override everything or do I have to make everything by my own. For example my ls color does not change. Is there anything which will make a consistent terminal coloring (zsh, vim, ls colors).

I know that ls colors are defined by the dircolors (which have to be evaled by the shell). Termite uses its ~/.config/termite/config file to color itself.

Thanks for every reply
