How to Apply Colour Theory When Designing Your Signage - Our Guide


Any brick-and-mortar business owner knows the importance of having well-designed signage. Signage and Banners should not be overlooked as an important aspect of your business, they are one of the first things a prospective customer looks for when they see your business. As such, it is important to employ good design sense when it comes to custom banners. 

One crucial aspect of this good design sense is the right use of colours. With so many colours in the entire spectrum of human vision, it can be difficult to decide on which few are appropriate for your signage. As such, we have created this article that incorporates various techniques to help you determine which colours you should choose for your custom banner. 


Colour Theory

Colour theory is one concept that designers and artists use to create works that are pleasant to the human eye. It begins with the primary colours: red, yellow, and blue.

Anyone who has gone to preschool or attended at least one art class has seen the colour wheel in action. It features the primary colours and how their combinations can produce other colours and shades. The colour wheel might seem like a good way to show how the combinations of the primary colours work, but it serves an ever more important purpose.

Colour wheels are designed that way to show the relationship between specific colours. Colours that are on opposite sides often go together. These colours would then be called “complementary” to each other. On the other hand, analogous colours are three colours that are adjacent on the colour wheel.

Using these concepts, you can decide which colours go with others, making your job of finding and using colours in your signage much easier. 


Your signage must be eye-catching 

One of the first things you must consider is what you want your prospective customers to see or look at first when they come across your sign. This often means striking a balance between bold and more outstanding colours against neutral backgrounds to draw attention. 

This is where contrast comes in. A specific colour can look different based on the other colours and textures surrounding it. For example, red text would stand out in a pale blue background but might fade against an orange one.

You might also notice that this contrast is better depicted when colour theory is used. For example, a red square against a green background (its complementary colour) would appear far bolder.

Here is a list of visible colour combinations to choose from:

  • Yellow or white lettering on a black, dark blue, or red background
  • Dark blue, grey, or red lettering on a white background
  • White, black, dark blue, or red lettering against a yellow background
  • Black or red lettering on a light blue background


These are just some of the more common and basic colours, but if you familiarise yourself with the colour wheel, you can likely find more. 


Final thoughts

The prospect of choosing colours can be frustrating, but it could be easier with a good knowledge of colour theory and how colours can go together. Once you have this down, you can create a more eye-catching and attractive sign to lure in potential customers.
