Depending on brand my guess would be yellow is a light or mild clay. Every blue color that I have used has been more aggressive.
BTW non believers, I've used clay on super soft black paint and haven't ever saw a scratch caused by claying the paint. The secret is to use tons of lubricant. Also there is no better way to rid the paint of contaminants.
