If got bored of colour schemes present in the Konsole, you can try new ones.
Here's how.
Goto the following link.

Download the colorschemes.
Now, once you download the file, unzip it.
In the sub-directory you can fine konsole colorschemes.
Copy them to one of the 2 directories , depending upon your linux distribution.
1. ~/.local/share/konsole
2. ~/.kde/share/apps/konsole
Open konsole
