Locked Ability to exclude programs from being affected by High Contrast theme

[mohracall]

Hi, As the title says, it's self explanatory, how could I exclude programs from being affected by the High Contrast theme I have chosen. Is there a process for it or does it need a custom edited theme (this came into my mind when I saw FBConan using it on his builds to achieve full dark theme kind of OS)
Thanks.

@FBConan do you mind providing how you did it for the Full Dark themes on your builds? I noticed they go through the applying transition of a high contrast theme but they're normal in all other apps, like what settings you changed & such for the theme files.
