What colors hurt your eyes the most?
Yellow, pure bright lemon yellow is the most fatiguing color. Why? The answer comes from the physics of light and optics. More light is reflected by bright colors, resulting in excessive stimulation of the eyes.
Bright white and cool fluorescent tube bulbs and incandescent bulbs emit the most UV radiation and cause the most damage to your eyes.
Thanks to the cone cells in the retina, our eyes are sensitive to various wavelengths of light, which gives us color vision. There are three types of cones, with maximum sensitivity to blue, green or red light.
Blue is the hardest color to see as more light energy is required for a full response from blue-violet cones, compared to green or red.
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.
Human eyes most sensitively respond to green color, peaking around 555nm. Newton observed that color isn't inherent in objects.
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
Yellow light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast.
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these.
Those warm colors you think about (red, orange, yellow, and some violets) are noticeable and convey security. They seem to move toward the eye, and they bring a sense of comfort and warmth. Cooler colors (blue, green, some violets, and yellowish-green colors) remind us of nature.
What is the most feminine color?
Pink, up to the 16th century, was considered a shade or red and was generally associated with the men. Only at the beginning of the 20th century it became a feminine color. This “gender change” occurred because of Elsa Schiaparelli and her creation of the iconic Shocking Pink.
The study found statistically significant gender differences in relation to yellow, white and green-yellow. All three colors were perceived as more attractive by women than by men. Results from our study show that chromatic colors have been perceived as more attractive than achromatic, with exception for black.

Legendary is a soft, gray, millennial beige with a silvery undertone. It is a perfect paint color for a living room or exterior home.
So What's the Truth About Dog Color Blindness? Having yellow-blue dichromatic vision means that dogs are most similar to a red-green color blind person. They are very good at distinguishing between variations of blues and yellows (and whites and grays), but cannot really see red and green all that well.
Warm light is best for the eyes. This includes filtered natural light and light produced by incandescent and LED light bulbs.
Therefore, the best color temperature LED for your eyes is anything in the warm white color temperature range (2700-3000K). Since clarity and contrast is a big part of lessening eye strain, a color-corrected type like our warm white Chromalux® LED might also be a great option!
Bright colors in particular can be harsh on our eyes - but they also draw our attention. Think about the color yellow. In lighter shades, yellow is comforting and cheerful. But when the brightness is cranked up, yellow can be a stimulant on the eyes.
Your brain interprets the various energies of visible light as different colors, ranging from red to violet. Red has the lowest energy and violet the highest.
Blue light has the strongest impact. Exposure to blue light (and white light, which contains blue light) during the sensitive period can make it difficult for you to fall asleep and stay asleep. Exposure to white light during the day can have positive effects, including boosting alertness and mood.
The best night light colors for sleep are red and amber, as they are warm and soothing colors that promote a good night's sleep. It's thought that colors close to red on the light spectrum stimulate melatonin production.
