The atoms of glowing gas emit the wavelength of radiations which lie in its spectrum. The same wavelength it can absorb because these are suitable for excitation pass through th gas
Chlorophyll is a protein that absorbs certain wavelengths of light during photosynthesis in plants.
Objects appear to have certain colors because they reflect or absorb certain wavelengths of light. The color we perceive is the result of the wavelengths of light that are reflected back to our eyes. For example, an object appears red because it reflects red wavelengths of light and absorbs other wavelengths.
The color of an object are defined by the wavelengths of visible light that the object reflects. This reflected light is picked up by our eyes and interpreted as color. The other wavelengths of light are absored.
A substance that gives color by reflecting some colors of light and absorbing other colors of light is known as a pigment. Pigments absorb certain wavelengths of light and reflect others, which gives them their characteristic color.
Waves given off by hot glowing objects are called electromagnetic radiation, which includes visible light, infrared radiation, and ultraviolet radiation. The specific wavelengths emitted depend on the temperature of the object - the hotter the object, the shorter the wavelengths emitted.

A hot, glowing wire emits all wavelengths (or colors) of light. This is sometimes called "blackbody radiation." Since all colors are present, you will get a continuous spectrum.

It separates the light by their wavelengths to make a color spectrum, and gives one a rainbow.

The plant is not absorbing light from wavelengths in the red and yellow range of the visible light spectrum. Instead, it is reflecting these wavelengths which gives it its reddish-yellow color.
The color of the object that you see will depend on the wavelengths of light that are reflected. Objects appear a certain color because they absorb certain wavelengths of light and reflect others. White light contains all colors of the spectrum, so the color you see is the result of the wavelengths that are reflected by the object.
The color of an object is determined by the wavelengths of light that it reflects. When light shines on an object, certain wavelengths are absorbed and others are reflected, and it is these reflected wavelengths that determine the color that our eyes perceive.
Visual perception is a result of light being detected by your retina at the back of your eye. Light of different wavelengths determines colour. Objects that are a specific colour absorb light of certain wavelengths and reflect light at other wavelengths. So if an object is green that is because it is absorbing the red and blue light and reflecting green.
