Metal Ions and Colors: Find Yours!

[Kyoma]

From what I know, different metal ions produce different colours. This is due to the fact that electrons jump to the next energy level when energy is absorbed but then released some of that energy back, producing different wavelengths and thus different colours.

What I want to know is whether there is a table that lists all metal ions with its respective colours? I don't want to know 'why' or 'how', 'cause it's too difficult for me to comprehend, but rather 'what'.

Many thanks.

The same ion can have many colors, depending on the composition of the substance.

I have never seen such a table. It depends on many factors like liquid, solid, counter ion, crystal form etc. The colored ions are mainly the transition metals found in the middle of the periodic system. It would be easier if you gave a hint of what you are looking for...
