What individual properties determine which color when split from white light is absorbed?

White light splits when it hits different particles in the air. From there different colors are sent out and absorbed by various things. A certain cell in grass allows grass to absorb more green, hence it gives off a green color. What would determine the color of wood for instance? And if wood is considered, would the density effect the tint/shade of the brown?What individual properties determine which color when split from white light is absorbed?
White light is not split up by different particles in the air (the exception are water droplets in a rainbow, the blue sky and the orange and red of sunsets and sunrises). Objects outside the atmosphere reflect back their colors, without white light being broken up by air. The moon is yellow, Mars is red and look at all the colors of Jupiter.








White light is made up (already contains) the different colors of the visible light spectrum: Red Orange Yellow Green Blue Indigo Violet. (Roy Green bit Iris Vaughn is a mmemonic to remember the colors)





What distinguished the different colors in the spectrum is their wavelength. When white light hits an object like grass or wood only the color you see the object as, is reflected, the other colors are absorbed.
