In Vtiger 7 user can add color comments by using our Advanced Comments extension. It is simply an enhancement to existing comments functionality. It adds up to two picklist fields to the comments section and allows the user to “categorize” comments added. In addition, comments are highlighted based on the configured picklist value, which makes it even more useful. In addition, it supports rich text formatting in comments

How to Add Custom Fields in Comments

1. Go to Menu > Settings > CRM Settings > Other Settings > Comments(Advanced). Name the picklist and click on the Green button next to the save button to add a new Custom Field. 
2. Click on the “+ Add Value” button to add a new Custom Field. 
3. Enter a value name and select a color. 
4. Here you can see the added Custom Field.
