$\huge\fcolorbox{pink}{Red}{ ★silver \: chloride᭄✍︎}$

Silver chloride gets easily decomposed on exposure to light as it is a photosensitive compound. It loses its opaque white appearance on disintegration by light into elemental chlorine and metallic chlorine. This reaction is used in black and white photography and films.
