Help your project pop with the right palette.

Choosing the perfect paint colour can feel overwhelming, but with a little understanding of colour theory, you’ll be able to create a stunning space that reflects your style and personality. At Bristol Paints, we’re here to guide you every step of the way, offering expert advice and high-quality products to bring your vision to life.

The Basics of Colour Theory

At its core, colour theory is about understanding how colours interact with each other and the emotions they evoke. Here’s a quick breakdown:

  • Primary Colours: Red, blue, and yellow – the foundation of all other colours.
  • Secondary Colours: Green, orange, and purple – created by mixing primary colours.
  • Tertiary Colours: These are the in-between shades, like teal, vermillion, or chartreuse, formed by mixing a primary colour with a secondary colour.

The Colour Wheel

The colour wheel is a fantastic tool for understanding how colours work together. Use it to create harmonious combinations:

  • Complementary Colours: Colours opposite each other on the wheel, such as blue and orange, create bold and striking contrasts.
  • Analogous Colours: Colours next to each other on the wheel, like yellow, yellow-green, and green, offer a more subtle and cohesive look.
  • Triadic Colours: Three colours evenly spaced around the wheel, such as red, yellow, and blue, bring vibrancy and balance to your design.

The 60-30-10 Rule

When planning your colour scheme, follow this tried-and-true rule:

  • 60% Dominant Colour: This will be the main colour in your space, typically used on walls.
  • 30% Secondary Colour: This supports the dominant colour and is often found in furniture or large décor items.
  • 10% Accent Colour: A pop of colour used sparingly in accessories like cushions, artwork, or vases.

Start Small, Test Big

Not sure where to start? Begin with a small project, like a feature wall or furniture makeover, before committing to a full room. At Bristol Paints, we offer discounted sample pots, so you can test your favourite shades in your space before making a final decision.
