Product ideas

I have thought of Earth, Fire, Air and Water as that are 4 different elements yet are all connected as they are a group. When typing these four words into google they all have their own colours, for example fire is orange, water is blue, earth is brown but can be green and air is a really light blue almost white.
Here are some images :

This image shows earth as brown but i think i would prefur the colour green to represent the leafs and trees.

I really like this and this would be something i would look at for my brand logo but change it as this has already been done. maybe have 2 circles one smaller than the other to the bottom right with these colours.

For each bottle i will need a name but for customers to see my product more easily i am wanting to use one colour for each element and maybe a symbol.
