Putting colours back into your energysystem is really easy to do. All you need to do is to go into meditation en relax.

First of all you need to make sure it is silent around and if you are  comfi, now you can start with the first/ root chakra. Imagine a red light coming from the cosmos finding its way to your chakra, imagine that all blockages and negetive energies are gone and going up to transform once you feel it is done you need to take back the colours of your chakra wich came into your energy field ( this happends on the moment you feel a emotion fitting to the chakra )  back into the chakra. What you need to do by that is to say aloud or inside to take back all the energy wich is from this chakra to go bak in the chakra. You feel or see that the energy in, in same colour ofcourse as the chakra going back in. After that you can ask to the chakra to give it the right position wich is best for you at the moment do that by thinking of  a flower or a camera opening or closing. Keep in mind that you never should close a chakra otherwise you stop your own enegrgy stream.

This method you can do with all the other chakra's ( remember to use the right colour )
