Find the right grey for your home
Red brick homes
Dark greys add definition, while softer shades create a more understated finish.
White/cream render
Pale render works well with darker greys for a clean, contemporary contrast.
Stone homes
Muted greys complement the natural variation and character of stone.
Traditional properties
Mid/light greys refresh older homes without overpowering character.
The three grey directions
Dark and dramatic
Deep greys create strong contrast and make windows, doors and garage doors a more prominent part of the exterior. They work especially well with dark roof tiles, black guttering and modern glazing.
Examples: RAL 7016, 7015, 7024
Balanced and versatile
Mid greys add clear definition without making the frontage feel too heavy. They pair well with a wide range of brick, render and roofing colours, making them a practical choice for whole-house spraying.
Examples: RAL 7037, 7036, 7031, 7040
Light and subtle
Pale greys provide a softer alternative to white and help exterior UPVC blend more natually with stone and cream render. They are also well suited to larger window areas and conservatories.
Examples: RAL 7038, 7035, 7047, 7001
Best grey RAL colours for red brick homes
Red brick can support several different shades of grey, but the right choice depends on how much contrast you want.
- RAL 7016 Anthracite Grey
- RAL 7015 Slate Grey
- RAL 7024 Graphite Grey
Tip: Look beyond the brick itself. Dark roof tiles, mortar, guttering and paving can all help a grey feel more connected to the rest of the property.
Best grey RAL colours for white or cream render
White and cream render or cladding can carry stronger greys because the pale background creates a clear separation between the walls and the UPVC.
- RAL 7016 Anthracite Grey
- RAL 7021 Black Grey
- RAL 7037 Dusty Grey
Tip: Cream render often works more naturally with muted or balanced greys, while bright white render can support darker shades.
Best grey RAL colours for stone homes
Stone contains natural variation, so the most successful greys usually share its softer, less uniform character.
- RAL 7038 Agate Grey
- RAL 7037 Dusty Grey
- RAL 7015 Slate Grey
Tip: Compare samples with several areas of the stone rather than one block. Natural stone can vary significantly across the same elevation.
Best grey RAL colours for traditional homes
Grey can update a traditional property without making it look overly modern, provided the shade does not overpower the existing features.
- RAL 7038 Agate Grey
- RAL 7035 Light Grey
- RAL 7015 Slate Grey
Tip: Traditional homes often benefit from a softer overall scheme, with darker grey reserved for one or two focal features.
5 things to check before choosing grey
- Check your home in different natural light (morning, evening and night)
- Look at surrounding materials (brick, stone, roof, render)
- Consider your garden and landscape colours
- Think about long-term style, not just trends
- Use our online Spraying Visualiser tool
Refresh existing UPVC without replacement
