If you use the GENERIC kernel:

The colormap has 32 entries, the first 4 are used for 2 bitplanes:

grey, black, blue, white

The program iteconfig can change the display parameters including depth
and colormap.


If you use the WSCONS kernel:

The console code has fixed colors for 1,2 or 3 bitplanes.

1 -> black, grey
2 -> black, red, green, grey
3 -> black, red, green, brown, blue, magenta, cyan, grey

The default is 2 bitplanes and you see grey-on-black text and a red cursor.

This is done by the wscons driver (default for e.g. x86). For Amiga
you need the WSCONS kernel.

You probably want WSCONS or build your own kernel.

http://www.netbsd.org/docs/guide/en/chap-tuning.html#tuning-kernel

should give you a start.

makemandb and fontcache are the heavy weights, but mostly on the first
start or after an update.

If your Amiga is networked, you probably want most other things sooner
or later, even postfix.

If you have a smaller Amiga (say less than 32MB RAM), you definitely
want a custom kernel that is stripped to the functionality you
need.
