Materials, Colours & Specifications
A turnkey specification should tell the site what to buy—not just what the room should feel like.
Mood images establish direction; procurement needs specifications. For major items, the BOQ or schedule should identify enough information to price and replace the item consistently—manufacturer or approved equivalent, model or range, dimensions, finish, thickness or grade where relevant, quantity, installation responsibility and any approved sample reference. A line that only says 'marble', 'wood finish' or 'lighting' leaves too much room for commercial and quality disputes.
Colour ratios are useful starting points, not engineering rules. For a quiet neutral residential scheme, one digital concept palette could use Warm Oat #E6DFD3 as the dominant field, Chalk White #F4F2EE as a lighter secondary and Soft Charcoal #3A3B3C as a controlled accent. A biophilic scheme could combine Grounded Moss #4A5D4E, Cognac #B07C57 and a Brushed-Brass visual reference #C5A059. An executive scheme could start with Midnight Navy #1D2A44, Alabaster #F0EAE1 and a Burnished-Gold reference #D4AF37.
HEX values are digital communication tools, not paint or metal specifications. Screens, daylight, CRI, sheen, substrate and surrounding materials change how a colour reads. Final paint, veneer, stone, fabric, laminate and metal selections should therefore be approved using physical samples or mock-ups under the actual project lighting before bulk ordering.
For clients who like a numerical framework, the 60-30-10 colour rule can help create hierarchy: roughly 60% dominant background, 30% secondary material or colour, and 10% accent. The 70/30 approach is slightly different and is often used to keep one style or visual language dominant while a smaller contrasting layer adds personality. We use either as a composition aid when helpful—not as a formula that overrides the architecture or the client's preferences.
