CSS Prism was created to quickly display the colors used in any CSS file, with basic color find/replace editing functionality. CSS Prism is beta software with some limitations:
- CSS cannot be uploaded from a local file
- CSS cannot be extracted from files behind firewalls or on servers that require authorization
- CSS files are not yet brought in via @import statements
- CSS files are cached for 5 minutes after being downloaded from each server unless &cache=0 is added to the URL
- Colors cannot be properly extracted when more than one color appears on a line. Compressed CSS files are particularly troublesome
