Yes, that's exactly how session management works. Is this solution not satisfactory (aside from 
the colors issue)?

It the menu you get by right-clicking in Yakuake terminal. It allows you to set fonts, colors, 
etc. Once you've done that you need to select "Save as default" from the menu. An alternative is 
to select "Use Konsole settings" to have Yakuake always mimic Konsole settings (as the option 
name implies).

I actually know nothing about these command-line color options - can't help here.

Yes, that's exactly what you told it to do :-) That `cd ~` is not a command executed in yakuake 
but in the shell process that is running the script. If you want a newly opened shell to start in 
a particular directory you can do this by editing your ~/.bashrc. I don't know how to execute a 
script on yakuake start, but I suppose that's doable. Try googling this.
