Was in the store tonight and got told these three colors (Solid White, Silver [old], and Blue [old]) were going away. The grey is unchanged (other than the name) from the current grey (otherwise known as new grey or steel grey and now known as midnight silver). Warm Silver has been renamed to Titanium (which was the name we were calling from leaks). Ocean Blue is now Deep Blue. Name changes are per an email from Elon according to the store employee.
