CMYK vs RGB: How to Choose the Right Colour Model for Your Business in New Zealand

In the world of design, colour plays a crucial role in how your business communicates its brand identity and engages with customers. Whether you’re creating a logo, designing promotional materials, or developing a website, choosing the right colour model is essential to achieving the best results. The two most common colour models CMYK and RGB are used for different purposes, and understanding their differences can make a significant impact on your business’s marketing efforts.

In this blog, we’ll break down the key differences between CMYK and RGB, and help you decide which colour model is right for your business in New Zealand.

What is CMYK?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black) - the four ink colours used in colour printing. CMYK is a subtractive colour model, meaning it works by subtracting light from white to create colours. When you combine these four inks in varying amounts, you can create a wide range of colours for print.

How CMYK Works:

  • Cyan absorbs red light.
  • Magenta absorbs green light.
  • Yellow absorbs blue light.
  • Black is used to deepen shadows and add definition.

CMYK is the industry standard for any kind of physical printing, such as:

  • Business cards
  • Brochures and flyers
  • Billboards and posters
  • Product packaging

In New Zealand, printing companies and design agencies predominantly use the CMYK colour model for high-quality physical marketing materials.

What is RGB?

RGB stands for Red, Green, and Blue, and it’s an additive colour model used in digital displays such as screens, monitors, and televisions. Unlike CMYK, RGB combines light to create colour. When red, green, and blue light overlap, they produce a broad spectrum of colours.

How RGB Works:

Red, Green, and Blue light blend together to create different colours. When all three colours are combined at full intensity, they produce white light. Red and green create yellow, red and blue create magenta, and blue and green create cyan.

RGB is used for any digital work, including:

  • Websites and social media
  • Online advertisements
  • Email newsletters
  • Digital presentations

For businesses in New Zealand, RGB is the go-to colour model for online branding and digital marketing.

Key Differences Between CMYK and RGB

  1. Colour Range
    RGB produces a broader spectrum of colours than CMYK. This is because RGB uses light, which allows for brighter, more vibrant hues, especially in neon and fluorescent tones. CMYK, however, has a limited colour range due to the physical properties of ink, resulting in more muted tones compared to RGB.
  2. Usage
    CMYK is ideal for printed materials. It delivers accurate colour replication on physical surfaces.
    RGB is best for digital platforms like websites, mobile apps, and any media displayed on a screen.
  3. File Formats
    CMYK is typically associated with file formats like PDF, TIFF, and EPS, which are used for high-quality printing.
    RGB is commonly used for JPEG, PNG, and GIF files that are optimised for web use.
  4. Colour Accuracy
    CMYK provides greater accuracy when printing as it directly correlates to ink colours. RGB colours may look vibrant on screen but could appear significantly different when printed, especially if not converted properly into CMYK before printing.

How to Choose the Right colour Model for Your Business

1. Determine Your Primary Medium

Are you primarily creating materials for print or digital platforms? If you’re focusing on print, CMYK is the obvious choice. If your materials are meant to be viewed on a screen, RGB will offer more vibrancy and flexibility. Many businesses in New Zealand use a combination of both for a consistent brand presence across both online and offline channels.

 2. Consider the Final Output Quality

If high-quality printing is important for your business (e.g., for brochures, packaging, or business cards), choose CMYK. You’ll get more accurate colour reproduction, ensuring your printed materials match your brand’s colour scheme.

On the other hand, if you need your digital marketing to pop with bold, vibrant colours, RGB is your best option.

3. Convert Colours Carefully

If your project will be used in both print and digital formats, you’ll need to carefully convert colours between CMYK and RGB. For example, when preparing a logo for both print and web use, ensure your designer creates versions in both colour models to avoid any discrepancies in colour appearance.

4. Test Before Finalising

Before sending your design files to the printer or publishing them online, run tests to ensure colour accuracy. Many businesses in New Zealand work with professional printers and designers who can provide proof prints for CMYK or test on multiple screens for RGB to ensure your brand’s colours look their best.

Why Getting the Right colour Model Matters in New Zealand

As businesses across New Zealand continue to compete in both the physical and digital space, choosing the correct colour model is crucial for maintaining brand consistency and achieving professional results. Whether you’re a local startup or an established brand, understanding the difference between CMYK and RGB can save you time, money, and headaches.

With New Zealand’s thriving business landscape, attention to detail in both print and digital design can help you stand out from the competition. Making the right colour choices enhances your brand’s credibility, communicates your message effectively, and ensures your marketing materials—whether printed or digital—look professional.

Colour Models and Accessibility: Designing for Everyone

When selecting between CMYK and RGB, businesses must also consider how their colour choices impact accessibility—particularly for individuals with visual impairments. Accessibility in design ensures that everyone, regardless of their visual abilities, can engage with your brand, whether through printed materials or digital platforms. For New Zealand businesses, inclusive design is not just a social responsibility but also a key factor in reaching a wider audience.

How CMYK and RGB Affect Accessibility

Both CMYK and RGB colour models can influence the accessibility of your designs in different ways:

CMYK (Print): When creating printed materials, ensuring proper colour contrast is critical. Certain colour combinations can be difficult for colour-blind individuals to distinguish, so high-contrast pairings, such as dark text on light backgrounds, are essential for clarity. Additionally, in CMYK printing, muted tones or complex colour overlays can make designs harder to read for those with low vision.

RGB (Digital): On digital platforms, colour contrast and clarity are even more important. The RGB model allows for brighter, more vibrant colours, but those colours need to meet specific contrast requirements to be readable for all users. For example, text and background colours must have sufficient contrast to ensure legibility, especially for users with low vision or colour blindness. RGB’s flexibility in brightness and hue makes it easier to achieve this, but it also requires careful planning.

Best Practices for Creating Accessible Designs

To make your business’s designs accessible, whether in CMYK for print or RGB for digital use, follow these best practices:

Ensure Adequate Colour Contrast

High contrast between text and background is one of the most important factors in creating accessible designs. This is especially true for web and mobile interfaces. Tools like the WebAIM Contrast Checker can help you ensure your RGB colour choices meet the WCAG (Web Content Accessibility Guidelines), which suggest a minimum contrast ratio of 4.5:1 for normal text. For printed materials, test your CMYK designs in grayscale to verify if they remain legible without relying solely on colour.

Use Colour Blind-Friendly Palettes

About 1 in 12 men and 1 in 200 women worldwide are affected by colour blindness. To create inclusive designs, avoid using colour combinations that are difficult for colour-blind individuals to distinguish, such as red and green or blue and yellow. Tools like Coblis (a colour blindness simulator) allow designers to check how their RGB or CMYK designs look to colour-blind users.

Text and Iconography Alternatives

In both digital and print design, never rely on colour alone to convey important information. Ensure that text labels or recognisable icons accompany any colour-coded elements. For example, if you use a red warning sign, include the word "Warning" or a clear symbol that reinforces the message. This way, people with visual impairments can still interpret the information without needing to differentiate colours.

Optimise for Low Vision

For both print and digital media, using larger fonts and simple, bold graphics helps ensure that users with low vision can engage with your content. In the digital realm, this is especially important, as users may view your content on screens of different sizes. Designs in RGB should be responsive, with easily scalable elements that maintain clarity across devices.

The Importance of Inclusive Design in New Zealand’s Growing Digital Landscape

In New Zealand, inclusivity and accessibility are becoming increasingly important as more brands and businesses move online. The New Zealand Government Web Standards emphasise the need for accessible websites and digital content, ensuring that businesses cater to users with disabilities. This trend is crucial for companies aiming to create a positive brand reputation and expand their reach.

Inclusive design not only helps individuals with visual impairments but also enhances the overall user experience for everyone. By designing with accessibility in mind, businesses in New Zealand can tap into a broader audience and demonstrate their commitment to social responsibility. This approach fosters stronger relationships with customers, ensuring that no one is left out when interacting with your brand.

As the digital landscape continues to grow and evolve, the need for accessible, inclusive design will only become more critical. Businesses that take the time to incorporate accessibility into their colour choices, whether through CMYK for print or RGB for digital, will stand out in the market and contribute to a more inclusive and equitable society.

Conclusion

Choosing between CMYK and RGB depends on your business’s needs, whether it’s for print or digital. While CMYK ensures accuracy for printed materials, RGB is essential for vibrant digital marketing. By understanding these two colour models, you can confidently make the right choice and keep your business’s branding consistent across all platforms.

If you’re working with a design agency or printer in New Zealand, don’t hesitate to ask about colour conversion and the best practices for your specific project. In the end, your brand’s colours are more than just hues—they represent your business to the world.
