The current Birla Opus site provides a strong benchmark for a paint website because it connects product discovery with brand families, colour discovery, services, contractor discovery, guides and product education.
Birla Opus currently separates Interior paints, Exterior paints, Waterproofing, Enamels, Wood Finishes, Wallpapers, Tools and Aerosols. Its brand architecture includes One, Calista, Style, Alldry and Allwood.
The current brand page groups One as a luxury range, Calista as a premium range, Style as an economy/value range, Alldry as waterproofing and Allwood as lifestyle wood finishes.
The current site has a colour catalogue with colour families, curated collections and a colour-profile quiz. Islamia can adapt this into a multi-brand colour discovery journey without claiming access to manufacturer shade databases unless the relevant source is available.
The current catalogue exposes Favourite and Compare interactions on product cards. Islamia's multi-brand catalogue can extend this into comparison by brand, surface, finish, purpose and verified technical attributes.
Birla Opus connects users to dealer stores, UDAAN contractors and painting-service journeys. Islamia can adapt this locally around Kolkata/Topsia without implying that Islamia is part of the Birla Opus service network.
The current site includes painting guides and beginner terminology. Islamia's existing technical library can provide a deeper, multi-brand version of this educational layer.
