Implementing a plasma colorscheme generator

[Andrew]

I have made a simple program that generates a plasma colorscheme from an 
image. I am hoping to integrate it into plasma, making it so it takes the 
current wallpaper (or any image) and allows the user to generate a colorscheme 
based off of that.

However, I am unfamiliar with working with large codebases such as KDE, so I 
am not sure where to start. Could some one point me in the right direction, 
by, for example, telling me where the files that the system settings for the 
colorschemes are? 

Sorry if I am doing something wrong, this is my first time using a mailing 
list.
