Understanding Colour: The Basics of Colour Science
Why Colour Matters in Everyday Life & Interior Design
Colour is a powerful force that shapes our everyday experiences. Ever noticed how fast-food chains use reds and yellows to spark hunger, or how hospitals favour soft blues and greens to create a sense of calm? Colour is a crucial part of any interior space. Whether you’re an interior designer, decorator, handyman, or architect, understanding colour theory helps you make better design choices, improve the atmosphere of a room, and even influence how big or small a space feels.
Choosing paint colours is not just about picking a shade you like—colours interact with each other, reflect different types of light, and can completely change the overall look and vibe of a space. With so many options available, having a structured approach to colour selection is essential to avoid any clashes and disappointments. Whether you’re working on a residential renovation, a commercial project, or a simple room refresh, knowing how to use colour theory can be the difference between good or flipping amazing.
The Colour Wheel: The Basics of Colour Theory
When you’re still in the planning stages, before even picking up a paintbrush, let’s talk about the colour wheel—a faithful guide for understanding colour psychology and creating coordinated and stylish colour schemes for homes.
Primary, Secondary, and Tertiary Colours
- Primary Colours: Red, blue, and yellow—the building blocks of all other colours.
- Secondary Colours: Orange, green, and purple—formed by mixing two primary colours.
- Tertiary Colours: Think of these as in-between shades like teal or vermillion, created by blending primary and secondary colours.
Warm vs. Cool Colours
- Warm Colours (Red, Orange, Yellow): Energising, inviting, and perfect for social spaces.
- Cool Colours (Blue, Green, Purple): Calming, peaceful, and ideal for chilled spaces like bedrooms.
Pro Tip: Want a small room to feel larger and more open? Go for cool tones! Looking for warmth and cosiness? Opt for warm shades.

Understanding How Colours Influence Mood
Colour isn’t just about aesthetics, it shapes how we vibe and move through a space. Interior design trends in 2025 are focusing on natural, earthy tones that create a sense of peace and harmony, perhaps an antidote to our fast-paced, tech and social media-driven lives. Soft sage greens, warm terracotta, like this one from Simply Colour, or muted lavender are rising in popularity as they blend seamlessly into modern aesthetics while offering psychological benefits like cosiness, comfort, and calmness.
Choosing Paint Colours: A Step-by-Step Guide
With so many options, choosing the right paint colour can feel like a total mission. But don’t stress—these steps will make the process a breeze:
- Assess Natural Light in Your Space: Lighting changes how colours look—test swatches on different walls and observe how they appear in morning (with your coffee), afternoon (while hydrating on H2O), and evening light (while sipping on a sundowner).
- Consider Room Function and Atmosphere: Match your colours to the purpose of the room:
- Relaxing spaces call for cool tones like blue or green.
- Social areas are best experienced with warm tones like Simply Colour’s terracotta red, warm yellow, or rich orange.
- Work with Existing Décor: Your wall colour should complement and elevate furniture, flooring, and textiles, not clash with them!
- Test Colours Before You Commit: Sample pots or test swatches, like Simply Colour’s Peel + Stick Swatches, are your best friend! Visualise what the colour will look like with a small trial section before going all in.
Common Colour Mistakes and How to Avoid Them
It’s easy to mess up when choosing paint colours to fit with your interior home décor. Avoid these common mistakes:
- Choosing Colours in Isolation – Always consider how your chosen shade will look in natural light and against your furnishings. Take a swatch and hold it against a couch or curtain.
- Ignoring Undertones – Some neutrals have hidden pink, blue, or yellow undertones that may not match your décor. Always test samples in different lighting conditions to ensure the colour blends naturally with your unique space.
- Overusing Bold Colours – Accent walls add drama, but go overboard and your space might start screaming instead of speaking. Keep it bold, but balanced!

FAQ: Your Colour Queries, Solved
Still unsure? Here are some common colour-related questions, answered:
What’s the best colour for a home office?
Green and blue promote focus and reduce eye strain—perfect for productivity and lowering stress levels during busy, multi-tasking times.
How do I make an open-plan space feel cohesive but not boring?
Stick to a consistent base colour and vary shades or accents from room to room. For example, if you choose soft greige as your foundation, you can add depth with navy, forest green, or warm mustard accents in different zones to create subtle separation.
What’s the safest colour choice if I plan to sell my home?
Stick to warm neutrals like greige, soft white, or taupe. They appeal to most buyers, make spaces look brighter, and give potential homeowners a blank canvas to work with.
Can I mix warm and cool tones in one space?
Absolutely! The trick is balance. If you have a cool-toned wall colour (like grey or blue), add warm elements through wood finishes, textiles, or accent décor to keep the space from feeling too cold.
The bottom line is: have fun, experiment with colours you’ve never tried before, trust your instincts, and create a home that feels uniquely yours. For a paint colour range that will get you excited, go to Simply Colour!
