Hello! I voted for the black solar shades, but think about how much natural light you get in your space. If the natural light is very intense, the darker color will naturally help tone that down more than a lighter color. Also keep in mind that the shades should have some transparency so even if it's black, you're still letting light through! If you're concerned about heat, the darker color will naturally absorb more, but if that is a major concern, you can get the solar shades lined with an anodized aluminum (or similar material) that reflects some of the light away, keeping it cooler. There is also some new technology out there called KoolBlack that doesn't use the lining but doesn't absorb the heat. Good luck and enjoy your new house!
