How to Select Custom Colour Combinations for Your LED Neon Sign 

 Designing a custom LED neon sign is more than just choosing the right words — colour selection plays a huge role in how your sign feels, fits your space, and grabs attention. Whether it’s for a home, business, event, or streaming background, the colour combinations of custom neon signs can elevate the entire look and feel of your setup. 

At NeonHub NZ, we help Kiwis bring their neon ideas to life with vibrant colour options, modern styles, and high-quality craftsmanship. But if you’re unsure what colours to pick, here’s a guide to help you make smart, stylish choices. 

1. Match Your Neon to the Room It’s In 

Before you dive into choosing neon colours, start with your space. Look at the tones already in the room: 

• Neutral rooms (like beige, white, or soft grey) give you more freedom to play with bold, bright neon tones like hot pink, electric blue, or vibrant green. 

• Dark or moody rooms work great with high-contrast colours like white, red, or warm yellow to make the sign pop. 

• Colourful spaces? Consider a complementary colour combo — colours opposite on the colour wheel (like blue and orange, pink and green) often pair beautifully. 

Tip: Hold a colour swatch or test light next to your wall to see how it feels in the natural lighting of the space. 

2. Explore Current Colour Trends 

Trends can give you a helpful starting point — and right now, certain hues are especially popular: 

• Pastels (like lavender, mint, peach) are trending in interior design and make great choices for signs in bedrooms, nurseries, or event backdrops. You may need a dimmer to help reflect these paler colours. 

• Cool tones like aqua or icy blue give a futuristic, clean vibe — perfect for gaming setups or tech-inspired branding. 

• RGB  (allows you to select a colour dependant on the day or mood ) are eye-catching and modern — a great fit for signage at events, salons, or bars. 

You can use our neon sign generator to experiment with different combinations and preview how they look together. 

3. Consider Visibility and Contrast 

The point of neon is to stand out. So make sure your colour combo has enough contrast: 

• Light colours like white or yellow work well on darker walls. 

• Darker colours like blue or red look better on light backgrounds. 

• Avoid mixing colours that are too similar in brightness — for example, yellow on white may look washed out in a well-lit room. 

For outdoor signs or bright spaces, high-contrast colours will always deliver better visibility. 

4. Make Your Brand Colours Shine 

If you’re creating a sign for your business, use colours that reflect your brand. This creates consistency across signage, logos, and interiors. You can even upload your own logo and we’ll turn it into a custom neon sign in your exact colours. 

Not sure what colours represent your brand best? Warm tones (like orange and red) suggest energy and passion, while cool tones (like blue and green) lean more toward trust, calmness, and freshness.
