RiversideRocks I assume that you are looking for the primary & secondary color values that are used at this forum. In that case, this was already discussed here: https://discuss.flarum.org/d/8256/7
TL;DR:
Primary: #E7672E
Secondary: #3C5675
Colored header seems to be off, as it is... well, not colored
I've checked the colors in the API, and they haven't changed since
