The colours & Shades of KNX - Decision Making when it Matters!

Choice is an interesting thing. When faced with limited options it’s often easy to work out what you want. Presented with just two options you could decide on the flip a coin. Regardless of the actual result, by the time the coin has landed you will know your preference. 

The more options you have though, the harder it gets to make a decision. This is amplified when the difference between the options is great. Picking a shade of paint for example is a fairly low impact choice. The differences are minimal as is the impact and final outcome. 

However, if you are trying to pick between totally different paint colours, the decision is much harder. The impact is obvious, and your mind must work harder to visualise the effect each colour will have on the space.

So much choice...

With over 500 manufacturers now all a part of the KNX association, there has never been more choice. 

Some items, such as power supplies, are fairly straight forward to select. They all fundamentally perform the same task and while there might be differences in the price or some additional features that guide your decision, reliability is really the key factor.  
This is an example of picking your shade of a single colour paint to use our earlier analogy. The impact on the project will be minimal and so the energy used to decide should also be small.  

Where it gets a lot more complicated is KNX switches & pushbuttons. There are literally thousands of different options when you consider the number of manufacturers, number of styles and the ranges of finishes. Even when you stick with a single manufacturer, you will see a huge range of choice.  
We all have our own preference when it comes to KNX keypad options. Style, colour, optimum layout of buttons, all subjective choices. It could also be based on functionality, for example the need for an integrated humidity sensor.

Ultimately though, it’s the customers decision as they are the ones that will be looking at the product in their house. The challenge is offering enough choice so that the customer will find something they like, but not offering so many that you end up with decision fatigue and the wrong choice being made.

The customer needs to enjoy the process. If the journey to find the perfect keypad was a chore, everyone would be using standard electrical switches in white plastic.

Helping the decisions making process

  • It is human nature to decide what we don’t like first, then select whatever is remaining as our preference
  • This is why it can be useful to have some widely different designs in your product portfolio
  • Start with the overall design and focus on the button styles
  • Once this is done you can turn your attention to finishes, which is a much easier decision as its usually based on the interior design

The key is to guide and support the customer in the decisions. Letting them run wild and choose whatever they find on the internet can make supply and support difficult, even when working with a standardised system.

KNX means a complimentary colour palette 

Whilst most of the product decisions on a project can be straightforward, it can soon add up to being a lot to work out. 

Thankfully there are distributors worldwide that specialise in navigating the complex world of KNX. They will offer you the support needed to select the right products. 

Of course, you still have to choose between the different distributors, but this is usually a decision based on customer service, availability of product and the level of support they can offer. 

That is where a distributor comes into their own. They can help you navigate hundreds of manufacturers to ensure the right portfolio is offered to customers and ultimately the decision-making process is full of choice without causing fatigue. 

A distributor makes picking the paint colour easy, supplies a quality product and is there for you if anything goes wrong!


Ultimately, KNX is a system that gives you the flexibility to choose from a huge range of products and solutions with the assurance that, regardless of your decision, the products will work together. 

This ease of compatibility also ensures manufacturers continue to develop their products, improving factors like reliability and performance. Worst case, you can always change to a different manufacturer if you aren’t happy with your decision. 

If only all life’s decisions were so easy to change!
