Re:Relativity gives gold its color

You don't get isotopes by adding or removing electrons. You'd need to alter the number of neutrons for isotopes. And that doesn't normally change the color.
If you would add or remove electrons from your gold particles, you'd need to keep the electrons somewhere close-by e.g. keep them with your anions. If you separate a lot of atoms from their electrons--you get a blob charged matter. To get all the atoms in 1 mol of gold (around 200g, say in a small cube) to each lose one electron and put the mol of electrons somewhere else, you'd need some non-trivial amount of energy. (Sorry, I am currently to lazy to calculate it..)
