A colored awning absorbs a tremendous amount of heat. White reflects the sun, as do light-colored decks. Teak decks are pretty, and make great non-skid, but they are impossible to walk on in the heat. The same goes for a colored hull. Just imagine that beautiful dark blue sailboat, with blue awnings, and teak decks.
Most people think it's white.
Irish Mist has full awnings and a large hard bimini. It is very important to have an awning for the fore deck, and covers for any large windows. Textiline is a plastic mesh that you can see through, but still allows light to come through. Whatever your sunshades are made of, they must be able to come down quickly. Give a lot of thought to this.
