Blue is one of the rarest of colors in nature. Even the few animals and plants that appear blue don't actually contain the color. These vibrant blue organisms have developed some unique features that use the physics of light.
Yellow is widely recognized as the happiest color in the world and comes with a scientific pedigree to back up this esteemed honor. Research has suggested two main reasons why yellow is considered the happiest color. Many studies have linked the psychological powers of yellow to the sun.
Red is a highly popular color in marketing because it's bold, captures attention and can evoke powerful psychological responses. Red represents power, energy, excitement, passion and urgency.
Examples of complementary color combinations are: Red and green; yellow and purple; orange and blue; green and magenta. Complementary color combos tend to be bold, which is why sports teams often use this formula for their colors.
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."
Yellow is the colour of inspiration, happiness, and the sun (the power source of life). It also symbolises communication, self-esteem, and power. Even scientific research state that the hormone associated with happiness increases by yellow colour.
Red: Excitement, energy, passion, love, desire, speed, strength, power, heat, aggression, danger, fire, blood, war, violence, all things intense and passionate. Pink symbolizes love and romance, caring, tenderness, acceptance and calm.
Rather, it is physiologically and psychologically perceived as a mixture of red and blue. So technically, magenta doesn't exist. Our eyes have receptors called cones for three different colors: red, green, and blue. By combining the three colors in different ways, secondary colors can be created.
Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Warm colors include red, orange, and yellow, and variations of those three colors. Red and yellow are both primary colors, with orange falling in the middle.
