Hi, how can i set a different color for the msg that i receive and those that i send ?

You will need to do some HTML/JS and CSS modifications for that in freichat/client/freichat.js

What do I have to change exactly in freichat.js ?

It is recommended that you wait for the next release , we will me making the JS modifications that will be needed for the colors , in the next version .
So then you will only need to make a few CSS mods .

Sorry , we accidentally deleted your last comment .

We have now made the required changes for changing the text colors of from message and to message ( including from name and to name) .
You can now edit these colors directly from the theme maker in the backend in the new version .

We should be releasing the next version by end of this week .

Thanks !!
