red and yellow
The reddish-yellow color of the leaves indicates that the pigment is absorbing blue and green wavelengths of visible light. This is because pigments appear as the complementary color to the wavelengths they absorb - in this case, absorbing blue and green results in the reddish-yellow color we observe.
The yellow and orange pigments in a chloroplast are carotenoids, such as beta-carotene and xanthophylls. These pigments help capture light energy for photosynthesis and broaden the range of light wavelengths that can be absorbed.
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 a pigment is determined by the wavelengths of light it absorbs and reflects. Pigments that appear yellow absorb shorter wavelengths of light, reflecting longer wavelengths which we perceive as yellow. Green pigments absorb longer wavelengths, reflecting shorter wavelengths which we perceive as green.
Barium typically emits green and yellow light, so its emission lines in the visible spectrum are likely to fall within the green and yellow regions. This corresponds to wavelengths around 570-580 nm for green light and 590-610 nm for yellow light.

Pigments that appear yellow absorb shorter wavelengths of light, reflecting longer wavelengths which we perceive as yellow. Green pigments absorb longer wavelengths, reflecting shorter wavelengths which we perceive as green.
An object appears yellow because it reflects wavelengths of light in the yellow part of the visible spectrum and absorbs other wavelengths. Our eyes perceive this reflected light as the color yellow.
Visible light, which consists of a range of wavelengths between approximately 400 to 700 nanometers, produces colors that are visible to the human eye. This range includes all the colors of the rainbow - violet, blue, green, yellow, orange, and red. When light strikes an object, certain wavelengths are absorbed and others are reflected, which determines the color that we perceive.
The pigment that reflects orange, yellow, and red wavelengths while absorbing other colors for photosynthesis is called carotenoids. Carotenoids play a crucial role in assisting chlorophyll in capturing light energy for the process of photosynthesis.
Various chemical constituents in whatever is colored absorb some wavelengths and scatter back the rest. The wavelengths that are not absorbed give you what you see. So something that absorbs all colour wavelengths except yellow, will look yellow. Absorption happens when particular atomic structures have energy levels which match the energies of incoming photons which may be in the visible, or infra-red etc.
Carotene reflects orange wavelengths on the visible spectrum.
Bananas appear yellow because they reflect yellow wavelengths of light and absorb other colors, such as blue and green. This absorption and reflection of certain wavelengths create the perception of yellow color in bananas.
Gold absorbs and reflects certain wavelengths of light, resulting in its characteristic yellow color. Blue light has a shorter wavelength than yellow light, causing it to be absorbed rather than reflected by gold. This is why gold appears yellow and does not reflect the color blue.
