Viridian
Composition and Properties of Viridian
Viridian is hydrated chromium oxide Cr2O3 • 2 H2O. This form of chromium oxide contains water molecules in its crystal structure and is of vivid color with a bluish tint. It is called viridian in English and vert émeraude in French.The pigment chromium oxide green with the formula of Cr2O3 is similar to hydrated chromium oxide but does not contain water molecules in its crystal structure. Its appearance is rather dull and more in the direction of olive green.Both variants are chemically stable and resistant against boiling acids and alkalis. Chemical stability and general permanence are some of the most important advantages of these pigments which are also compatible with all other pigments.

I told you long ago, Silver, either manipulate or be manipulated. Pokemon are nothing more than tools. People are nothing more than tools. After they've served your purpose, they're no longer useful… … MEWTWO. Kill him! Who: Giovanni Source: Tarnished Gold Notes: Much like the aforementioned Lost Silver, this is a non-canon hack of Pokemon Gold/Silver, set in the perspective of the game's rival. However, it instead follows the story of how Silver tries to scramble his way through the Pokemon world, resorting to stealing in order to get on through the Pokemon League. Eventually, he ends up in Viridian City, finding it to be completely deserted. Entering the gym, he finds heavily mutilated bodies lying on the floor before witnessing Giovanni kill Gold and his Typhlosion. Giovanni then speaks the above sentence of how Pokemon and people are nothing more than tools for others, to be disposed of when their purpose has been served. After this, his Pokemon Mewtwo turns against Giovanni, killing him through torturing him then ripping his head off.
