All Dogs have dichromatic vision which allows them to perceive fewer colors like shades of blue and violet clearly, able to distinguish yellow and lighter shades of these colors, and not able to see greens and reds but may appear as shades of gray and brown to them. Dogs rely on other senses like hearing smell to understand their environment better. 

Dogs cannot see colors as humans do. Color differentiation can be possible due to cones and motion with different light levels can be detected through the retina. The two types of cones (dichromatic cones) help to discern shades of colors not actual colors as trichromatic cones do. It can be assumed that dogs are red-green color blind.

Dog vision compared to humans

Based on genetic factors, dichromats have two cones and are able to represent their visible gamut and trichromatic cones in humans have three types of photoreceptors that are most sensitive to long, short and medium wavelengths. 

The amount of rods in the eye is higher in dogs which helps to identify objects in the dark and also differentiate moving objects at a fast rate. The dogs may get distracted from a far distance like a bird flying from 40 meters and bark at him.

What colors can dogs see more clearly?

The red-green perception of color blindness is considered  abnormal in color detecting molecules. It is all due to cones in the retina, the human eye consists of retina lining within the eye that is able to capture incoming photons and transmit them along neural pathways, convert light into electrical signals for the brain to perceive a visual image. In some people these photoreceptors are missing that won’t be able to detect certain wavelengths and called color blindness. 

In animals especially in dogs the same phenomena of photoreceptors would recognize and result in dogs not seeing some specific colors. Red-green makes them appear gray and brown to them.
