Is it possible to access VS Codes theme properties programatically? Like, can a person use the VS Code API to change a theme color?

Programmatically Accessing VSCode Theme Properties

Is it possible to programmatically & dynamically get & set the colors of V.S. Code's theme property's using the V.S. Code API?

The snippet bellow demonstrates using The VSCode API, and its method, getConfiguration(), to change settings. I was hopping that something like this snippet would work from programmatically changing theme colors, but to no avail.

    const workbenchConfig = vscode.workspace.getConfiguration('workspace');
    const themeColor = workbenchConfig.get(`colorTheme.${themeProperty}`);

    console.log(themeColor)

 
    // The argument colorTheme.${someColor} would is obviously replaced with the       
    // theme's property that I want to access.

I wanted to access the same object that the workbench.ColorCustomizations setting accesses, using the snippet above. My thinking was that I could set the theme colors in the same scope, that is used by workbench.colorCustomizations setting, but my attempt was without success.
