Different Colors of Dice for Different Things

Is there a way to choose different colors of dice to be rolled for poison, acid, etc. damage so it can be displayed what damage was from a regular attack and what was from say poison?  Also, choose a separate color to indicate normal damage vs the dice that were rolled for critical hits or a way to query critical hits as opposed to automatically rolling them. Right now in my game when a player rolls an attack from their character sheet it automatically rolls critical damage unless they choose not to roll damage, then they have to bring up the dice roller to roll each damage and damage type.  It would be nice if it only rolled critical damage if the d20 hit in the critical range set on their sheet.  A query for sneak attack would be great too. 

As to your problem of damage types, I don't think there is a way to do that inside Roll20.  There may be a way for Stylus (an extension) to do that but it would be sheet dependent.  Regarding the problem your player is having, which character sheet is it? There might be a resolution to the problem itself.
