How do I use document.body.style.backgroundcolor in an if statement

I want to create a button that switches between light and dark colors, so basically this works:

JavaScript

document.body.style.backgroundColor = "gray";
if (document.body.style.backgroundColor == "gray") {
    document.body.style.backgroundColor = "red";
} else {
    document.body.style.backgroundColor = "blue";
}

But this doesn't:

JavaScript

document.body.style.backgroundColor = "#2a2a2a";
if (document.body.style.backgroundColor == "#2a2a2a") {
    document.body.style.backgroundColor = "#840000";
} else {
    document.body.style.backgroundColor = "#008400";
}

I don't want to limit myself to the premade colors of HTML, i want to have my own custom color scheme but at this time it does not seem possible.

What I have tried:

I tried using preset colors, and it worked. I don't want to use this way.

It is because backgroundColor is an rgb value, not a string. For example add

JavaScript

alert(document.body.style.backgroundColor)

right after you set it and you'll see it is not the string you just set it to. It does work, you just can't test for the background color that way.

If you want to test for the background color's hex value there is some code that looks like it will work, javascript - How to get hex color value rather than RGB value? - Stack Overflow[^]
