If I understand your issue correctly you are having trouble getting your font color to adjust and stay on your jotform properly. Is that correct?
However, be advised that if you've previously done this then you would need to adjust the existing css similarly to update the font color correctly.
If you continue to have issues with this then please provide us with the link or the name of the jotform in your account along with telling us more about what part of your form you are having the font color issue with and we will gladly help you out more.
