A few classmates and myself are making a little music playlist windows form application for practice and I would like to code a button click event that allows the user to change between a couple of themes. So far I can manage to have the colours change no problem on a single form or even on multiple forms but the issue I'm having is that what I have so far doesn't seem like a very elegant solution.

​

if (BackColor==DefaultBackColor)

{

this.BackColor = Color.DarkGray;

f.BackColor = Color.DarkGray;

}

else

{

BackColor = DefaultBackColor;

f.BackColor = Color.DarkGray;

}

Basically right now I would be changing each individual forms colours manually on the button click and I'm wondering if there would be some easier solution like a global variable or a way to pass the changes between forms. I don't need a solution just a little nudge in the right kind of direction.
