There are some businesses that make the majority of their money at night – think liquor stores, night clubs, casinos, and even emergency rooms. If yours is a business looking to compete for the after dark dollars, your signage could be making a big impact on your effectiveness. The human eye sees some colors more easily than others, especially at night. Choosing the right color for your sign could make all the difference for viewing after dark.
Red and white are the two best choices. White is a great option because it reflects all the colors of the light spectrum. This makes it more visible when there is less light. Other colors, such as blue or black, will absorb whatever small amount of light is available but the white will reflect it. White can be further highlighted by pairing it with a contrasting color. Take highway signs for example – white lettering on a green background. They have figured out that your eyes will pick-up on the white, day or night, if it’s layered on top of a colored background. During the day the colored background helps the sign continue to get attention, while at night the white does the trick.
Red is another good color for viewing at night. The reason for this is because the human eyes uses 3 types of cones – blue receptive, green receptive and red receptive – in order to see color. These cones are clustered in the center of the pupil where they pick-up color based on its wavelength. The longer the wavelength the more easily the eye picks it up. Red has the longest wave length, 610-700 nanometers compared with violet at 400-450 nanometers. Below a certain wavelength your eyes can not pick up color at all, you simply see shapes or outlines of objects rather than their color. The longer wavelength of red makes it one of the first colors to become visible in the dark. It takes far less light for your eyes to pick up red than violet.
If you need your sign to really pop at night, red and white are your best choices. Infinity Signs, NW can also add halo lighting to illuminate your sign from behind.
