HMG Paints and the Painting and Decorating Association have identified Chartwell Green as the dominant exterior colour trend for 2026. The forecast stems from analysis of current spec and design patterns across residential and commercial projects in Britain.

Colour trends in exterior applications carry practical weight for contractors. They influence material orders, client expectations and project scheduling across the financial year. When a single tone gains market momentum, supply chains adjust and labour demand patterns shift accordingly.

Chartwell Green's ascent reflects broader aesthetic movement toward muted, heritage-influenced tones in British facades and garden schemes. The shade sits between traditional grey-green heritage palettes and contemporary neutral demand. For painters and decorators, this trend translates into stock planning and customer consultation shifts during winter specification seasons.

The timing matters: contractors should monitor HMG and PDA colour forecasts in Q4 to align supplier relationships and material budgets for the 2026 season. Early adoption of trending colours can strengthen client positioning and reduce lead-time pressures when demand spikes.
