You can load new color definitions into the color database using read-color-db and load-color-database.
Given a color definition file 
my-colors.db
 of lines like these:
#(:RGB 1.0s0 0.980391s0 0.980391s0) snow
#(:RGB 0.972548s0 0.972548s0 1.0s0) GhostWhite
(load-color-database (read-color-db "my-colors.db"))
To clear the color database use the form:
(setf *color-database* (make-color-db))
Warning:
 You should do this before starting Common LispWorks (that is, before 
env:start-environment
 is called) and be sure to load new color definitions for all the colors used in the environment when you do start it. Those colors are determined  from the 
config/colors.db
 file.
You can remove a color database entry with 
delete-color-translation
.
