A brown color is a color
combination of red, orange and green--those colors are not adjacent
in the visible colors of a rainbow so they do not combine to form
a visible brown. The colors which normally make up the BROWN color,
however, ARE ALL PRESENT in a rainbow, but are not present in the color
combination we call brown.
Note: I found this statement in the Ask a Scientist Physics Archive at
http://www.newton.dep.anl.gov/askasci/phy99/phy99125.htm On a computer or TV display, brown is generated as a sort of dim yellow or orange.
Color with the wavelength is a characteristic of light that corresponds to a specific range of electromagnetic spectrum. Different colors have different wavelengths, with red having the longest wavelength and violet having the shortest.
The color lavender is a combination of purple and white, with a wavelength range around 380-450 nanometers. It is perceived by the human eye as a light shade of purple with a slightly pinkish hue.
The next wavelength is infrared which can be considered as heat. My physics instructor told me that brown does not occur on the electromagnetic spectrum, since no combination of other color wavelengths can create it. The "color" brown is created by the brain as a filler. That means brown is imaginary in a way. This shouldn't be SO shocking, since the brain does other things to our vision like invert the picture so what we see is not upside-down. It makes me wonder though...when we see brown, there has to be SOME wavelength coming into our eyes, but not within the visible light range. What wavelength should brown be, then? There you go: an answer, but an even harder question that comes with it!
Peat can range in color from brown to black, depending on the decomposition level of the organic matter it contains.
Red has the longest wavelength among the visible light spectrum, with a wavelength range of approximately 620-750 nanometers.
The wavelength for the color red is 700-635 nm, which can also be said as 700 to 635 nanometers.
The wavelength of light brown color falls within the range of approximately 570-590 nanometers. This falls within the yellow to orange range of the visible spectrum.
750 nanometers corresponds to the wavelength range of red light.
The color red has the longest wavelength of all the colors in the light spectrum.
A color with a wavelength of 434 nm falls within the blue-violet range of the visible spectrum. This specific wavelength is closer to the violet end of the spectrum.
The color of a wavelength of 499 nm is blue-green. It falls within the range of colors in the visible spectrum between blue and green.
Color with the wavelength is a characteristic of light that corresponds to a specific range of electromagnetic spectrum. Different colors have different wavelengths, with red having the longest wavelength and violet having the shortest.
The color of light with a wavelength of 649 nm is red. This is because red light has wavelengths in the range of approximately 620-750 nm.
The color of a laser light depends on the wavelength of the light being emitted. Common laser colors include red, green, blue, and violet, with each color corresponding to a specific wavelength range.
The color yellow is created when light at a certain wavelength is reflected off an object and enters our eyes. Objects appear yellow when they reflect light in the wavelength range of approximately 570-590 nanometers. This specific wavelength range triggers the perception of yellow in our brains.
The color lavender is a combination of purple and white, with a wavelength range around 380-450 nanometers. It is perceived by the human eye as a light shade of purple with a slightly pinkish hue.
Pupfish range in color from silvery-brown to silvery-blue.
