Should a two-tone grey house use more light grey or more dark grey?

In general, light grey is the main colour on about two thirds of the walls and dark grey is the accent on about one third. Light grey reflects more heat and shows fading less in Phuket's sun.

Does painting a house grey make the house hotter?

Light grey absorbs about as much heat as other pale colours. Dark grey absorbs clearly more. For dark grey, avoid west-facing walls that take the afternoon sun, or keep the dark tone to areas shaded by the eaves.

Which colours go with grey apart from white?

Grey sits well with natural timber, black window frames and gutters, and the green of a garden. For warmth, pair a brown-leaning grey with timber. For a modern look, use a blue-leaning grey with white and black.

Does grey on an exterior wall show dirt easily?

Mid grey hides dust and rain marks better than white. Very dark grey shows salt deposits and water runs as white streaks more clearly, above all on houses near the sea.

Two-Tone Grey Exterior House Colours: How to Pair Them

Two-tone grey exterior house colours are easy to pair when a light grey is the main wall colour, a dark grey is the accent and the trim is white. Choose two greys from the same family, both blue-leaning or both brown-leaning, then test them as sample patches on the real wall before deciding.

How do you pair two-tone grey exterior house colours?

The most reliable way to pair two-tone grey exterior house colours is to use a light grey as the main wall colour, a dark grey as the accent in a smaller proportion, and white for the trim. Both greys must come from the same family: both blue-leaning, or both brown-leaning. A common split is about two thirds main colour and one third accent. This article is one of the colour and house painting guides from Phuket Pro Painters. The pairings are described in words and no manufacturer's colour codes are quoted.

"Two-tone" is the term Thai homeowners and painters use for an exterior painted in two wall colours, usually a lighter and a darker shade of one colour, plus a trim colour. Two-tone grey is popular because the scheme looks modern, suits box-shaped houses and newer housing estates, and hides dust better than plain white. Grey also changes with the light more than most people expect, so the choice needs to be made in steps.

How many families of grey are there, and which should you choose?

Grey is not one colour. Every grey carries an undertone, which becomes obvious once the paint covers a whole wall in sunlight.

Grey family	Impression	Goes with
Blue-leaning or cool grey	Clean, modern, cool on the eye	Black or grey aluminium frames, dark grey roofs
Brown-leaning or warm grey	Soft, warm, not harsh	Timber, brown roofs, natural stone
Neutral grey	Plain and neutral	Widely usable, but test in real light
Green-leaning grey	Blends with a garden	Houses surrounded by trees

The key rule is not to mix a cool grey and a warm grey on the same house. Side by side, one of them will look purple or green in a way nobody intended. Look first at the colour of the roof, the door and window frames and the paving around the house, then choose the grey family that leans the same way.

Which two-tone grey pairings work on real houses?

The pairings below are widely used. Choose by the character of the house.

Pairing	House type that suits	Worth knowing
Light grey with dark grey, white trim	Modern two-storey houses	The most basic pairing; gives clear depth
Smoky white with mid grey	Single-storey and small houses	Looks wide and bright, and stays cooler
Warm grey with timber or dark brown	Houses with timber slats or timber doors	Adds warmth and softens the grey
Light grey with near-black grey	Box-shaped houses that want sharp lines	Use the near-black sparingly, because dark grey absorbs heat

The two shades need to be far enough apart to look deliberate. If the light and dark are too close, the house reads from the street as one colour applied unevenly.

Which part of the house takes light grey and which takes dark grey?

A two-storey building painted light grey outside with a darker grey band between the floors and a red-brown tiled roof

There are several ways to place the two tones. Every method should follow lines the building already has, such as a render band, the edge of a beam or a wall corner. Do not divide a flat wall in the middle with no line to support the change.

Should the ground floor be dark and the upper floor light?

Dividing by floor, with the darker grey below and the lighter grey above, makes a house look firmly grounded. The ground floor also takes rain splash and dust from the ground, and a darker tone shows those marks less. The method suits two-storey houses with a band or canopy between the floors.

Should projecting and recessed parts take the dark grey?

On a box-shaped house where parts of the wall step forward, put the dark grey on the projecting or the recessed sections to bring out the form, and keep the main walls light grey. This method uses little dark paint and has a strong effect.

Should dark grey go on a feature wall only?

Choose just one or two walls, such as the wall beside the front door or the carport wall, for dark grey and paint everything else light grey. This approach suits single-storey houses.

Where should the white go?

White belongs on mouldings, window surrounds, eaves soffits and columns. White separates the two greys and sharpens the lines of the house. A white soffit also reflects light so that the area under the eaves does not look dark.

How do strong sun and greenery change grey?

Phuket's midday sun is strong and white, so every grey looks at least one step lighter on the wall than on the sample card. A very light grey can look almost white, and a mid grey looks light. If you want the wall to read clearly as grey, pick a shade slightly darker than the one you like on the card.

In the evening the sunlight turns orange-gold. A warm grey then looks brownish and a cool grey looks duller. A house surrounded by large trees or lawn picks up green reflected light on the walls, which makes a neutral grey look greenish. A house near the sea or a swimming pool picks up blue reflected light, which makes a cool grey look bluer still.

In the rainy season, a wet dark grey wall looks darker again and shows water runs as streaks. Walls that take driving rain are better in light to mid grey.

How do you test grey with sample patches?

Choose two or three light greys and two dark greys from the same family.
Paint large sample patches on the real wall, with the light and dark greys next to each other as they will be on the finished house.
Paint patches in at least two places: a wall that takes sun and a wall in shade.
Wait until the paint is fully dry, then look in the morning, at midday and in the evening, and on an overcast day.
Step back and look from the front of the house or from the road, because distance makes colours look lighter.
Compare the patches with the roof and the window frames, then choose the final pair.

What should owners of grey houses in Phuket watch for?

Dark grey absorbs more heat than light grey. A west-facing wall in dark grey gets hot and the paint film works harder. Dark shades also show fading more clearly after several years of sun, so use an exterior paint grade that the manufacturer states is UV-resistant and holds its colour well. Owners who want a house that feels cool more than one that looks sharp can also consider other cool-tone house colours.

Owners who like a two-tone scheme but want a warmer-looking house can compare the two-tone brown exterior pairings, which place the tones on the house by the same rules.

Does a two-tone paint job cost more than a single colour?

A two-tone job adds the work of cutting a clean line between the colours, and may mean buying two shades in quantities that do not use up full cans. The real cost depends on the area, the height and the condition of the walls. Estimated rates are on the house painting prices page.

Can the painter help decide where the two tones go?

Yes. During the site survey, the painter looks at the dividing lines of the building and suggests where the colour change can be cut neatly. Phuket Pro Painters surveys and measures the site free of charge and issues a written quotation before work starts, every time. Details are on the exterior painting service in Phuket page and the whole house and villa painting page.
