The Psychology of Colour: Green

There has been an extraordinary amount of research conducted into different colours and their powerful psychological impacts on human behaviour, mood and decision-making. This phenomenon — known as Colour Psychology — is one of the simplest yet most powerful tools used by marketers, interior designers and psychologists today.

And of all colours, green is one of the most powerful and emotionally resonant of all.

Why Green is So Psychologically Powerful

Green symbolises nature, growth, life and renewal. It appears in all forms of the natural world — plants, trees, vegetation, grass and animals — and our brains are hardwired to respond to it in deeply positive ways.

Research has shown that the colour green evokes feelings of abundance, peace, refreshment and security. It has even been shown to reduce stress, depression and anxiety while improving focus, impulse control and creativity.

One remarkable study placed participants in an indoor room with green walls and asked them to exercise. Compared to those in a grey room, this group experienced significantly less mood disturbance and perceived far less physical exertion — simply because of the colour surrounding them.

The reason? Evolution. Early humans learned that green in nature signalled food, shelter and water. That association is so deeply embedded in our psychology that it persists to this day — influencing how we feel in any space, whether we're conscious of it or not.

Green in Interior Design: The Rise of Biophilic Design

Only recently has the research into colour psychology and biophilic design really taken off — and designers across Australia are embracing it with extraordinary results.

Biophilic design is the practice of incorporating natural elements — plants, greenery, natural textures and organic forms — into built environments. The goal is to reconnect people with nature in spaces where they spend the majority of their time: offices, homes, restaurants, hotels and retail spaces.

The evidence is compelling. Studies show that biophilic design in workplaces can:

• Increase employee productivity by up to 15%
• Reduce absenteeism by up to 10%
• Lower stress levels measurably within minutes of entering the space
• Improve creativity, focus and overall wellbeing

For Australian businesses investing in office fit-outs, retail design or hospitality interiors, incorporating greenery isn't just an aesthetic choice — it's a strategic one.

Green in the Workplace

Consider a typical office environment. Employees are expected to sustain high levels of focus and creativity for hours at a time, often under fluorescent lighting in spaces designed for efficiency rather than wellbeing.

Now imagine the same office with a living green wall behind the reception desk, a cluster of large artificial fiddle leaf figs in the breakout area, and trailing artificial pothos plants along a shelf above the workstations.

The visual effect is immediate — but the psychological effect goes much deeper. The presence of green, even in the form of high-quality artificial plants, triggers those same evolutionary responses: calm, security, restoration.

Many of Australia's leading organisations — from Medibank to Starbucks — have already incorporated artificial green walls and statement plants into their spaces, and have seen measurable improvements in staff engagement and customer experience as a result.

Green in Hospitality & Retail

In hospitality and retail, the psychology of green has a direct impact on the bottom line.

Research consistently shows that customers spend more time — and more money — in spaces they find visually appealing and emotionally comfortable. Green walls, potted trees and trailing plants create an atmosphere of lushness and abundance that signals quality and care.

Restaurants incorporating greenery report higher dwell times and better customer satisfaction scores. Retail stores using biophilic design elements see improved conversion rates. Hotels with green walls and indoor plants receive higher ratings for ambience and atmosphere.

The challenge, historically, has been maintenance. Real plants in commercial settings require regular watering, pruning, pest control and replacement — a significant ongoing cost and operational burden.

That's exactly where high-quality artificial plants have become a game-changer for Australian hospitality and retail businesses. The psychological and aesthetic benefits of greenery, without any of the maintenance overhead.

Choosing the Right Shade of Green

Not all greens are created equal when it comes to psychological impact. Research suggests that medium-light shades of green — think sage, eucalyptus and soft olive — are most effective at promoting calm and restoration.

Deep, saturated greens can feel dramatic and bold — great for accent walls and statement pieces. Lighter yellow-greens feel fresh and energising. Silver-greens, like those of an olive tree, evoke a sense of warmth and timelessness.

When designing a space with greenery, consider the mood you want to create:

• Calm and restorative: Sage greens, soft eucalyptus tones, trailing plants
• Fresh and energising: Bright tropical greens, large-leaf plants like monstera and fiddle leaf fig
• Warm and timeless: Silver-green olive trees, dried botanicals, textured foliage

How to Bring Biophilic Green Into Your Space

Whether you're decorating a home, fitting out an office, or designing a hospitality venue, here are the most impactful ways to incorporate green:

Statement trees: A large artificial indoor plant — like a fiddle leaf fig, olive tree or palm — instantly anchors a room and creates a focal point.

Green walls: An artificial outdoor green wall brings dramatic biophilic impact to both indoor and outdoor spaces. Perfect for reception areas, restaurant feature walls, balconies and retail displays.

Trailing plants: Hanging and trailing artificial plants add softness and movement — ideal for shelves, above cabinetry, and in stairwells.

Clusters and vignettes: Grouping plants of varying heights and textures creates a more natural, immersive effect than single specimens.
