As there are a spectrum of different gray shades out there, with gray being an enduringly popular color for decoration in the home, we ask the question, what color is slate?

Named after the metamorphic rock of the same color, known for being used as a building material for flooring and roof tile designs, slate is considered to be a gray shade with beautiful blue undertones.

When planning room color ideas, slate can bring a sense of the outdoors into the home, as well as create a sophisticated, modern scheme, working well for both classic and contemporary interiors. A versatile neutral, when decorating with gray, working with the color slate can bring a timeless appeal to your chosen environment.

On the color wheel, slate is a tertiary color that is created through a mix of purple and green - a tertiary color is made when combining equal amounts of a primary and secondary color.

As slate is a mixed color, there are many different shades available, with some closer to dark gray and some closer to blue, however typically, slate is regarded as a gray shade.

Sue Wadden, director of color marketing at Sherwin-Williams (opens in new tab) states, 'slate, based on the rock material of the same name, is an earthy shade of gray that can range from deep to light.'

When using the color slate in interior design, whether through paint, soft furnishings, or the actual stone itself, the color offers an array of possibilities. Ideal for neutral room ideas, as well as for being bold with paint ideas, slate can be used to create both a subtle and striking effect in a space.

Justyna Korczynska, senior designer at Crown Paints (opens in new tab) states, 'different shades of gray are hugely versatile – they have more color and texture within them than straight black – a monochrome scheme of black and white is much more unforgiving than one of shades of slate and clay, which will change subtlety with the light throughout the day, giving them personality and character.'

Slate is popularly known to be a shade of gray, inspired by the natural colors and varieties of slate rock. As the color stems from a mix of purple and green, there are many slate shades with these subtle undertones, as well as others that are similar to different shades of gray.

As slate is a mixed, tertiary color, there are always going to be a variety of options to choose from when planning your slate décor ideas.

When looking at the color slate, there are often two main categories of slate shades to choose from, slate gray and slate blue.

As slate is a mixed color with blue undertones, there are many shades that are more blue or purple in appearance, however traditionally, and especially in reference to the color of slate rock, slate is considered a gray shade.

Patrick O’Donnell, Farrow & Ball (opens in new tab) brand ambassador states, 'slate is often perceived as a dark blue / gray – our perennially popular Railings would fit into this category at the darker end of the slate spectrum.'

There are a variety of shades to choose from, so when planning your slate décor ideas, deciding on a light or dark shade with blue or dark gray undertones is a good place to start.

When slate is paired with vibrant, bold accent colors, this color contrast can create a dynamic and elegant color palette for the home. In this hallway space, the bright orange chair and painted feature stripe work beautifully with the slate painted walls and white painted paneling - a great choice for accent colors for gray.

Justyna Korczynska states, 'I love gray in the bedroom – either a really watery tone for a bright and clean look, or a deep slate or charcoal for more drama. Really anything goes with either – a shocking pink, a touch of metallic, a deep mustard – you need to choose the atmosphere that you want to create, and decide whether that means you want to use deep and dramatic tones, or light and reflective ones'.

Slate can also create a grounding, relaxed environment when united with other, adaptable neutral shades, forming a calming environment with a reference to the outside world.

Sue Wadden states, 'over the past few years, we’ve begun to see popular tones of gray shift from cooler, modern tones to warmer hues inspired by nature. The earthy undertones in Slate Tile make for a grounding hue that pairs well with warm neutrals like Shoji White.'
