What color is the least often occurring in a natural environment?

The least often occurring color in a natural environment is royal blue. This color is not commonly found in flora and fauna, as most plants and animals exhibit colors that often serve purposes such as camouflage, attracting mates, or warning predators. Green is predominant due to the prevalence of foliage, while red and white appear in various flowers, fruits, and natural elements. Royal blue, however, is rare and not typically seen in the natural world, which is why it stands out as the color least likely to be encountered.
