When identifying the materials for your finishes, it's best to specify the manufacturer and their product to ensure that the render matches the final finishes.
By identifying the specific colours by paint code and/or manufacturer's colour name, the correct colours can be selected. Since blue to one person is a different blue to another; specifics are needed to ensure we're all on the same page. Additionally, your screen and my screen will not display colours the same, so please be sure to provide this information.
If non-specific colours are provided and used, yet are not what you're looking for in the render, there may be a fee to re-render.
Please be specific to help ensure we get the best possible result!
