Car enthusiasts know that depending on the color of the car, scratches on it may vary in appearance. If you damage the body of a black car, the scratches on it will be white, and vice versa, even if for comparison we take the same brands of cars made of the same material, but painted in different colors. In fact, this phenomenon is associated with optical illusion and the limited ability of the human eye.
What color are the scratches on the car?
First you need to figure out what color actually remains scratches on the machine in the event of a collision.
Before applying the paint, the outside of the car is covered with a special primer. It provides better adhesion of the paint to the surface and prevents the rapid formation of rust. It is light gray in color, since such a tone does not shine through and does not affect the tonality of the paint.
Interesting fact: if you paint the car without preliminary treatment with soil, the paint will begin to peel off and peel off after a month, and the driver will ride in metallic-colored vehicles.
During the appearance of scratches on the car, in most cases, only the paint is peeled off, since the soil has greater strength. Therefore, the true color of the scratch is light gray. If the vehicle got into a serious accident, then the soil can also be removed from the surface. Then the seam will be metallic in color, which is also close to gray.Why does a person see white or black scratches depending on body color?
Vision Features
To answer the main question of the article, you must first understand the features of human vision. Inside the eye there are lenses that allow you to focus on certain objects. That is why, if desired, people can clearly see a specific object and examine its details, while everything else remains vague.
However, focusing has its limits. For example, you cannot clearly see an object that is too far away or close to the eye: the lens simply cannot focus on it. The same rule works with small objects. A person cannot examine in detail something tiny against a monotonous background: the object simply merges with it. Therefore, the eye sees only color contrasts, and on a light surface, small objects appear darker, rather than dark - lighter.
Why are black scratches on white cars and white on black?
It must be immediately explained that if a scratch on a car has a thickness of at least several millimeters, then from a meter distance a person with normal vision will be able to see its gray tint, regardless of the paint applied to the car body. With sufficient lighting, light rays will fall on the ground or metal, so you can see the real color.
When a thin scratch appears on the body, a person cannot distinguish its color due to the too small area. The eye only picks up contrast with the general background, realizing that a defect is present on the surface.Accordingly, if the scratch is on the white urine, a person will see a black stripe, and if on black - a bright one.
If the car body is of a different color, the appearance of the scratch that a person sees will depend on the tonality and brightness of the coating. For example, on a dark blue background, the seam will appear lighter than on a yellow transport.
When a person looks at a black car, he sees a white scratch, and vice versa, because the eye cannot see the seam in detail. Because of this, people see only the contrast of surfaces, which appears due to the difference in colors.
