Why by change in oxidation state the colour of the complex chnage

1.	Why by change in oxidation state the colour of the complex chnage
Answer» Answer: If iron is oxidized, it LOST an electron, and the oxidation state is changed. ... When the transition metals combine with other atoms, some of their electrons get more energy. When this occurs, the electrons absorb light of a given wavelength. Remember that COLORS are different WAVELENGTHS, and this changes the color.

Answer:

If iron is oxidized, it LOST an electron, and the oxidation state is changed. ...

When the transition metals combine with other atoms, some of their electrons get more energy.

When this occurs, the electrons absorb light of a given wavelength. Remember that COLORS are different WAVELENGTHS, and this changes the color.
