In general, materials that appear colored usually absorb light of certain colors while reflecting others. The color that is absorbed depends on the material's specific properties and pigments. Without more specific information about the material in question, it is difficult to determine which color will be absorbed from NM (presumably short for "New Mexico").
At 700 nm, red light is being absorbed. This wavelength corresponds to the red end of the visible light spectrum.
If the wall reflects light in the 400 to 500 nm range and absorbs light in the 600 to 700 nm range, it would appear to our eyes as a color that falls within the reflected range (blue-green) and not in the absorbed range. The absorbed light would not contribute to the perceived color of the wall.
The color of light for 728 nm is in the red portion of the spectrum.
A wavelength of 540 nm corresponds to the color green in the visible spectrum.
A wavelength of 530 nm corresponds to green light.
At 700 nm, red light is being absorbed. This wavelength corresponds to the red end of the visible light spectrum.
If the wall reflects light in the 400 to 500 nm range and absorbs light in the 600 to 700 nm range, it would appear to our eyes as a color that falls within the reflected range (blue-green) and not in the absorbed range. The absorbed light would not contribute to the perceived color of the wall.
The color of light for 728 nm is in the red portion of the spectrum.
A wavelength of 540 nm corresponds to the color green in the visible spectrum.
Wavelengths below 350 nm are absorbed by Earth's atmosphere, primarily by ozone, oxygen, and nitrogen. Wavelengths above 750 nm are absorbed by the eye's photoreceptors, causing them to be outside the visible spectrum.
The most light absorbed by plants is in the blue (400-500 nm) and red (600-700 nm) wavelengths. This is because the pigment chlorophyll absorbs light most efficiently in these ranges for photosynthesis. Green light (500-600 nm) is least absorbed, which is why plants appear green to our eyes.
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 green color is being absorbed
A wavelength of 530 nm corresponds to green light.
If red light is absorbed, the color seen will be the complementary color of red, which is cyan.
Light with a wavelength of 470 nm is in the blue part 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.
