Google Sheets – Combine Checkbox and Conditional Formatting

Here's my problem.

I have a cell with a checkbox. I can make it turn green when I check it. But I want it to turn green if no conditions are met and turn orange when a condition is met. The condition is that a range of four cells is empty (<>""). If all of them are empty – then checkbox becomes orange when pressed, if there is anything in any of the four cell then checkbox becomes green when pressed.
