How to represent a data that is good/acceptable, and data that is not acceptable? Currently I am using green for good data and red for bad data with bold font. Please suggest.
Let me tell you the requirement briefly. Let's say in a website we have two fields- Field A and B. Field A is non editable but it's value will dynamically change as per the value entered in field B. Field A is basically a guideline filed and indicates the user whether the value entered in field B is permissible or not. In other words, if the value of field A is greater than 10 (let's say) then it is a bad value and user should get this message. Now my question is what is the best way to represent the field A. Currently I have thought of Putting Bold and color(Red) font to represent this.
