Why do we store silver chloride in dark-coloured bottles?

(N/A) Silver chloride $(AgCl)$ is a light-sensitive compound.
When exposed to sunlight,it undergoes a photochemical decomposition reaction to form metallic silver and chlorine gas.
The chemical equation for this reaction is:
$2AgCl(s) \xrightarrow{\text{sunlight}} 2Ag(s) + Cl_2(g)$
To prevent this decomposition and preserve the chemical,it is stored in dark-coloured bottles that block light.
