[FEATURE] Client can change color of rectangle for difference / excluded part.

[woosyume]

Is your feature request related to a problem? Please describe.

What

As a new feature, I'm suggesting that client can set color for rectangles with the difference.

Background

About my case,
When we release something, we run image comparison for before and after deployment.
It's job of internal automation app based on Selenium WebDriver.

But we sometime take time to find diff rectangle when it's exists because there are some other parts with red colored.
Maybe you can see it with the following page.

That's why I want to set other color so that we can find difference as soon as possible.

Detail

Describe the solution you'd like
Add a public method to ImageComparison.java to set color.
Sample

    public Color setDiffRectangleColor(Color color) {
        this.color = color;
        return this;
    }
...
        graphics.setColor(this.color);

Describe alternatives you've considered
Nothing special.

Additional context
Nothing special.
