Auxochrome — Chromophore

(...) waves between our hands. 

All of you in a space full of sounds — in the shade and in the light. You were called AUXOCHROME: the one who captures color. I CHROMOPHORE: the one who gives color. You are all the combinations of numbers. Life. My wish is to understand lines form shades movement. You fulfill and I receive. Your word travels the entirety of space and reaches my cells which are my stars then goes to yours which are my light.
