You mean this graph?
The red means you are out of the standard recommended range for each of those properties (see I’m really high or low on those), and the green is showing that I am in the standard recommended range for those properties. The graph below that shows the % of each of the fatty acids that give the soap its properties.
Yes, exactly. It doesn’t mean “stop!” but it means to take a look at it to make sure it’s what you want.
If you see the example above, almost all of my graph is red! BUT that doesn’t mean it’s not an awesome soap. It’s a salt bar with a huge 20% superfat. The idea of having green/yellow/red is not to stop you from making a soap that you know will be what you want- it’s simply to alert you that you may be out of the norm for a standard soap guideline.
