High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Deqing Demi Pigment Technology Co., Ltd. is the preferred supplier for architects seeking natural, high-performance colors. Our brown series is manufactured to provide a "Color Signature" for iconic buildings and landscapes. We focus on batch-to-batch repeatability, ensuring that large developments built over several years maintain the exact same brown hue across all phases. Our pigments are the choice for premium facade panels and landscape elements worldwide.

A: We use specialized homogenization equipment to "cold-bond" our blends, ensuring the particles stay together during transport and mixing.
A: Yes, our inorganic browns are fully compatible with lime and will not react or fade.
We offer a "Designer Match" service where we replicate natural soil or rock samples provided by architects to ensure the building perfectly integrates into its environment.
Sample Kits: We provide architects and designers with standardized "Let-down" charts showing how our browns appear in both grey and white cement at different dosage rates.
In architectural browns, color science focuses on the "Warmth Index." We use the a∗ (red) and b∗ (yellow) coordinates to plot a specific "Chroma Map." By adjusting the ratio of red to yellow, we can move from a "Cool Taupe" to a "Warm Mahogany." We monitor the "Luminance" (L∗) to ensure the brown provides enough contrast against other building materials. Our goal is to maintain a ΔE of less than 0.8 across multiple production years, ensuring visual continuity for long-term projects.
