According to Rina Patel, interior designer and founder, Vastu Interior Design, we should begin by drawing inspiration from nature. 

'Landscapes, pebbles on a bench, or bold peacock features can provide the stimulus you need,' she shares. 

'From this, focus on three colors – two which contrast and a more neutral shade. The tonal color can be used as a base for the room with the bolder hues creating focal points through accessories, such as lampshades.'

Using this ingenious color technique creates a seamless design scheme – so you can be more daring in your color matches, but keep your home stylish through a simple system. The rule suggests that colors arranged in odd numbers (especially 3) are more aesthetically pleasing and, consequently, more memorable. Plus, while this is the rule of three, experts sometimes branch to other odd numbers, which provoke the same effect.

Knowing how to use the colors is one thing, but choosing these shades is another. When searching for natural hues, Jen and Mar, the duo behind Interior Fox, suggests going back to basics and choosing a palette that is instantly associable with nature: green and blue. 

'Green and blue is a winning combination and one we as interior designers use as our neutral base. They are closely connected on the color wheel, so it's easy to introduce the two tones to create the illusion of more color without overpowering a space. Fresh, earthy, and completely versatile, you can't go wrong with green and blue,' they emphasize.

The designer duo then offers their tips for bringing these shades into our scheme, suggesting we 'tone up or down depending on the desired outcome.'

'For a calming effect, opt for lighter colors offset by natural finishes, or for a more sumptuous scheme, choose much darker shades. We find that darker hues add more shadows and different tones when the light hits and make the perfect backdrop for brass accents,' Jen and Mar add.

How should we use these earthy colors in our homes?

It is perhaps no coincidence that Etsy similarly named Sky Blue as their Color of the Year for 2021, and there is no better time to experiment with this shade than the present. Lucy Ackroyd, Head of Design at Christy, suggests injecting blue, and other raw colors 'in the form of cushions and throws'

'Keep the rest of the room minimal and white and weave in natural fabrics, such as jute and rattan, to create an organic, calming ambiance,' she explains.

'In feng shui, blue is considered a peaceful tone that promotes relaxation and healing, so it's the perfect shade for spaces you truly want to unwind in, such as your bedroom or living room,' Lucy adds.

While rules are made to be broken, the rule of three is one rule we're certainly going to follow by the book. We can't really argue with the experts, can we?
