Hi

Although this Q is more related to ImGUI, but since cinder has it integrated, i am wondering how to change the themes for ImGUI windows? I have attempted to search for the relevant color settings in some of the ImGUI cpp files, but I am quite lost (lots of files, plus vars aren’t very clear to me). If you could point me to the ImGUI source files containing the vars which are responsible for window colors (even in the cinder repo), that would be great.

Ahoj

Imgui has some built in style modes so you can see [how they do it](https://github.com/cinder/Cinder/blob/master/src/imgui/imgui_draw.cpp#L230-L283) and adapt it to your needs. The names are pretty self explanatory.
