Does the dichroic coloration show from both sides? Does it just register as a grey tint on one side and the color on the other? Does the static cling come in the 60� stance?

Yes, the color shows from both sides. Currently the only 60" version of this is an adhesive-backed material. It is available here: https://www.decorativefilm.com/sx-3065-spectrum-transparent-dichroic-film-sr-coating
