Help with colors and products

I am new to this product and could use some advice on colors and products to use for the desired look.
I want to paint the green Formica portion of this tabletop to look old, like the wood on the barrel it will be attached to.
I have contemplated using the gel stain with the antiquing gel over it. I am just not sure if that would be the correct choice to get the look I am trying to achieve, and if so, I have no clue which colors.
These tables will sit outdoors under a covered area, so they won’t get direct rain, but there will be moisture outside.
Any input advice would be greatly appreciated.
