We have the ability to change the default colours, logo, welcome message, success message and re-direct link on forms. Meaning you can put these settings in, and they will be on every form, unifying your message.
To do this, simply go to settings >> form settings.
Here you can change all the defaults for your forms.
Once saved, when you go to create a form you will see that you can select your default settings or change them for that particular form if you need too.
