You can find a possible kate colour theme attached.

Using a red background would also be a serious eye-catcher.

And the number of additional colours would not be > 8.
You suggestion was 5*12=60 colours.

We can reduce this number by  having the list background only for View, and 
the 7 numbered colours only twice (background and foreground).

This would mean 5*4+1+2*7=35 colours.

The 7 foreground colours would need to work with View and with all of the 7 
background colours.

For the other cases (Window, Button, Selection, Tooltip) we test whether the 
foreground colour or the background colour provides better contrast. This way 
we can catch cases where e.g. View has a light background and Selection a 
dark one. Perhaps we could even additionally increase the contrast a bit (but 
I don't think that's really needed.)
