sure.


r.colors map color=rules << EOF
0   106:255:89
200 106:255:89
200 139:255:77
400 139:255:77
400 178:255:64
600 178:255:64
...
2200 209:210:88
2400 209:210:88
EOF

You can save the rules file (saved in $MAPSET/colr/) to the
$GISBASE/etc/colors/ directory and then access it with:

r.colors rules=your_rules


see the other files there for an idea as well as the r.colors help page
  http://grass.itc.it/grass60/manuals/html60_user/r.colors.html


Also check out the use= option of d.legend?
