The Stella - Safari Stella is a unique and stylish frame that features a round shape and metal nose bridge and nosepads. The lenses have a gradient brown color with a darker brown at the top and a lighter brown at the bottom. There is also a metal detail near the temples. To complete this look, I would consider adding a bright pop of color to the lenses, such as yellow or pink, or a silver or gold for the metal details. This can highlight the mix of materials and will transform the overall look of the frame. Alternatively, to maintain a more subtle look, you can use earth tones for the lenses, like a deep teal or brown, and pick a similar tone for the metal accents.
