The colors of the rainbow, and a few that aren't in the rainbow to balance things out.
Gold is a heavy, soft, yellow metal that is easy to work with. It is the softest metal, and is very dense, much denser than lead.
Gold is very stable and is used to coat other more reactive metals to protect them, but its primary use is in jewelery. Pure gold is too soft to make jewelery out of, and is usually mixed with silver, copper and other metals.
Lavender is a small bush with greyish leaves and pale purple flowers. Lavender is also the name for the color of the lavender flowers.
Lavender flowers smell very nice and still smell nice when they are dried, so they are often used in potpourri.
An orange is the name for both a colour and a citrus fruit. Oranges are similar to lemons but are very sweet and can be eaten raw, squeezed to make juice, and can be made into marmalade. The colour orange can be made by mixing red and yellow paint.
