Blue Weather Skincare Visual Proposal

Design a brand visual proposal homepage for a beauty brand, themed 'design_theme'. The visual serves a fictional skincare brand's Key Visual (KV), avoiding common splashes or large facial models. Instead, it uses a translucent blue essence bottle, soft mist glass countertop, nighttime window view, and a thin film structure unfolding like a weather layer as the main visual. The composition adopts a vertical brand proposal cover feel, with the main product in the center and restrained layer relationships at the top-left and bottom-right, featuring ample white space. The lighting is low-illumination cold blue ambient light with extremely thin white bottle rim lighting, emphasizing glass thickness, liquid refraction, and packaging edges. The color system must include specific values: color_palette. Material descriptions focus on material_details. A small amount of dominant Chinese text is needed, including the brand name, a very short brand slogan, one English auxiliary subtitle, and a small function label, with a light, thin, and breathable layout. Suitable for brand KVs, website splash screens, launch event main visuals, and brand case study covers.
