I too have had slight problems finding darker brown.. I havent tried it yet..but in the past I have had great success dyeing plastics with powder rit dye, water & acetone. good thing is that the acetone makes the dye penetrate the plastic a few thousands of an inch so you can sand a bit without removing the dye. bad thing is that you have to have just the right amount of acetone for it to work.. to little..and the dye wont penetrate... too much and you melt the plastic..also..very critical..is the length of time its kept in the solution..so..it will take quite a few tries to get it right.. I would experiment on scrap pieces till I got it right. Another problem pertaining to making cues would be that you would have to glue the collar on the cue..turn it down to final size...remove the collar...dye it..then reglue it..since the dye doesnt penetrate too far.
