Why are colour modes important?
To get the optimal results on your projects, it’s important to understand the purpose of different colour modes.
There are a range of top-level benefits to learning about different colour modes, as they allow you to:
- Adapt your colours to each medium. By using colour modes, you can adapt your colours to each medium you use. The easiest example is made when comparing RGB to CMYK – one is ideal for digital mediums, whereas the other replicates print colours better.
- Ensure colour consistency across your designs. Colour consistency is made easy as colour modes let you identify the exact colours you’re using. This ensures there are no variations or slight changes to colour.
- Optimise your colours for display. Certain colour modes aren’t as detailed, meaning they can improve the performance of your website or application. For example, indexed colours could be ideal for use on a spreadsheet app or your brand’s website leading to better file sizes.
How to use colour modes for colour consistency.
If you use the same colour modes, printed designs and assets can often come out looking different and that’s because printing with ink is very different to RGB lights on a desktop or digital interface.
Here’s a quick rundown of additive and subtractive media, and their impact on colour consistency.
Additive Mixing.
Additive mixing is a method that makes colour by mixing light. This results in a spectrum of varied colours using Red, Green and Blue (RGB). When added together, these colours become light – if you mix all three, you get white. While it’s great for digital media, this method is also used on things like ambient lighting.
Just remember to calibrate your screen when mixing light and try to look at designs across screens as different settings could yield different results.
Subtractive Mixing.
Subtractive mixing doesn’t use light to mix colours – instead, it uses materials like dyes and pigments (or aims to replicate them). When you mix red, green and blue paint – you don’t get white, right? A subtractive mode like CMYK is the go-to way to print for packaging, posters and brochures.
When you use CMYK on a digital application, colours could look a bit different once printed. Try to print some proofs just to ensure things turn out the way you want.
Combining colour modes.
With both additive and subtractive colour methods, it’s always a good idea to make your own swatches so that once you’ve got the colours down, you’ve got a consistent reference.
Switching between modes can be a bit tedious because of the likelihood of colour changes. Tools like Adobe Colour Management can help keep your colours from shifting shades. With a bit of know-how, and a touch of preparation, you’ll be able to achieve consistent colours across your print and digital media.
