color-scheme and qt applications

[hamzeh]

I'm using LXQt as a desktop environment. Currently, I'm using the breeze as Qt/Widget Style for all of my Qt Applications. And now I want to update color-schemes of breeze. For example, the breeze has BreezeDark color set and I want to use it as default color set with some modifications. How can I do that? I don't want to use from 3rd party applications: systemsettings5 and ...

I did some changes in Breeze.colors and BreezeDark.colors files in the breeze project here, and build/install it on the system. But I couldn't change the color set.

Any sugesstion/comment/...?
