This particular color does a decent job of simulating older rubber, for a more modern rubber it is a bit on the brown side. For vintage components like aircraft tires it will do the job, but for a more modern piece of equipment like a rubber hose found on a more modern car you have to add a darker hue such as flat black in order to make the color a bit darker to get the proper appearance. This particular paint is marketed as being flat, but in my experience with the paint it tends to be more of a semi-gloss finish, so if you want the true flat appearance you will likely have to apply a flat finishing coat onto it in order to make it appear appropriately flat. Out of the jar it tends to have the vintage coloring for rubber, but the finish appears a bit new compared to the color, but as I said that is easy to fix by applying a flat top-coat.
