The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable. These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see.
Some wavelengths are easier for humans to see, and green is the most visible from a distance. There are receptors in the eye called cones that contain pigments that sense wavelengths which communicate with the brain which colors we see.
Darker colors absorb more UV than lighter colors like whites and pastels. This means the UV rays are less likely to reach your skin. But bright colors such as red can also absorb UV rays. The more vivid the color, the greater the protection—a bright yellow shirt is more protective than a pale one.
Pure white, being the most reflective color, is at the other end of the scale at 100 because it doesn't absorb light or warmth. Colors that fall below 50 on the LRV scale will absorb more light than they reflect. Shades above 50 help create a daytime look and add a feeling of expansion to a space.
There's also some scientific research indicating that due to the short wavelengths of cooler colors and how our cones perceive them, greens and blues are the most relaxing to our eyes. Easily put, greens and blues colors are simply less tiring to the eye."

Darker colors absorb more sunlight than lighter colors, which is why darker colors get warmer more quickly in the sunlight than lighter colors. The lighter colors reflect more of the sun's radiant energy, so they remain cooler to touch in the sunlight.
White snow and ice reflect the sun and keep the planet cool. Dark surfaces, however, like the open ocean or forests absorb sunlight and heat up. Scientists call this the albedo effect.
Snow and ice can reflect 50- 90% of incoming sunlight.
