You dream that your fingers are painted with black paint, which means that in order to create future happiness, you work selflessly with your hardworking hands. This finger painted with black paint is a testimony that you are not afraid of fatigue and embarrassment at work. If your fingers are covered with white paint, you are starting from scratch.
But then again, if you dream that your fingers are painted with red paint, the meaning will be different. This is a bloody hand!
I'm kidding you, don't mind!
Sweet dreams!
