Hi Gluu team, Recently I install gluu-server and wants to do some customization of UI. I modified lots of label according to your tutorial [https://gluu.org/docs/ce/3.1.2/operation/custom-design/](https://gluu.org/docs/ce/3.1.2/operation/custom-design/). But when it comes to header color, I do not know how to change it. Basically I need to change the `green` color of the image below to something else. [https://imgur.com/a/fSyVg](https://imgur.com/a/fSyVg) I found the color is from `skin-green` in `newtemplate.html`. And `skin-green` is defined in `oxtrust-static-3.1.1.Final.jar`. Is there a chance for me to modify the color to a customized color? say an orange color. Thanks you in andvance, Ches
