This second part focuses on three essential shades: orange, terracotta and green.
Less frank but deeper, these colours allow you to structure an interior, to bring warmth and to create a more natural and enveloping atmosphere.
Why do colours influence our interiors so much?
Colours have a direct impact on our perception of a space, but also on our state of mind.
Some shades boost energy, others promote calmness. Some visually enlarge a room, while others make it more intimate.
Natural colours such as green or terracotta are particularly used to create balanced and reassuring environments. Conversely, warmer colours such as orange can energise a space and make it more lively.
In interior design, the choice of colours is therefore strategic: it influences the atmosphere, the luminosity and the perception of volumes.

Orange: a warm and stimulating colour
Orange is a color associated with warmth, friendliness, and creativity.

Shades such as burnt orange are now very present in decoration trends, especially for their ability to create an atmosphere that is both modern and warm.

Terracotta is a color directly related to nature, stability and comfort.
It evokes raw materials such as wood or earth, making it an ideal shade to create an authentic and timeless atmosphere.
Very present in contemporary interiors, it fits perfectly into minimalist, bohemian or natural styles.

Combined with nature, it brings a feeling of freshness and balance. It is particularly recommended in areas dedicated to rest or concentration.
Shades like sage green or sea green are great for a soft vibe, while emerald green helps add a more elegant and sophisticated touch.
