The general category of elements that are probably not present in the solid if it is colorless is transition metals. Transition metals often contribute to the color of a solid due to their ability to have partially filled d orbitals that can interact with light to give colored compounds.

What are two types of elements in the periodic table?
If you are referring to the periodic table, then metals and non-metals, though if that is the case I should remind you that metalloids are also a category. Though if you were asking more broadly about molecules, as this category would suggest, you're probably looking for organic and inorganic.

Are all 109 known elements found in nature?
There are 92 "natural elements, and 21 manmade elements, for a total of 113 elements - all of which exists on earth.

Why can't we see oxygen?
When oxygen is not in a compound with some other elements, we don't see it becasue it is a colorless gas at the temperatures and pressures we normally encounter. You would probably be able to see oxygen in solid or even liquid form, but the environment would be so cold there be a hazard of immediate severe freezing or even death. Seeing oxygen is probably not worth that risk.
