The Colourblind® activity is a communication exercise which develops team building skills and helps teams recognize problems caused with imprecise communication and language.
It is a verbal problem solving experiential learning activity that is used to improve team problem solving and listening skills, and is played in a small group.

Communication skills, especially listening skills, are some of the most often-quoted soft skills demanded by employers, and identified as requiring to be developed further by its leaders.

This communications exercise provides a challenging activity to all levels of leaders, and typically becomes more challenging as the seniority of the group increases, where the ability to really listen and not just 'wait to speak' is often demonstrated.

Wearing blindfolds to ensure total dependence upon the quality of their verbal communication, a group works together to gather information that will allow them to solve a puzzle. The size of the group (ideally between 6 and 14) demands different types of skills: information and group management, active listening and questioning, strong chairing skills, the ability to clarify and summarise, the creation of a common language, and the need for feedback to ensure understanding.

Colourblind® is also now available as a fully online activity, providing a significant experiential challenge for remote groups. For further information on Colourblind® (online version) CLICK HERE.

  • Develop effective communication, team building, and problem solving skills
  • Set up and manage an effective communication system that everyone understands and can use efficiently.
  • Develop a dialogue which will lead to a common understanding of abstract concepts.
  • Deliver a successful solution to the problem they face.
  • To consider how to improve both communication systems and the quality of the messages which those systems support
  • To practise effective listening and refine questioning skills
  • To develop flexibility in communication skills, changing and adapting language to meet the needs of others
  • To understand communication is culturally specific 
  • Ensure we are using shared references to achieve common meaning

The materials supplied will enable you to work with the recommended group of up to 14 people. (If your group is larger then consider providing roles as observers rather than participants).

You will need enough working space to ensure that the large team can work together and hear each other – the ideal arrangement is probably a ‘horseshoe’ shape of chairs, so that seated and blindfolded participants can receive the plastic pieces in their hands/laps.

Each participant is blindfolded and issued with a number of small plastic pieces. The team has to identify the colour and shape of two pieces that were removed from the complete set of plastic pieces. 

A period of between 20 - 30 minutes intense verbal information exchange and problem-solving approaches will typically be required depending on the abilities within the group.

The design of the Colourblind® activity and the complexity of the pieces can lead to confusion, ambiguity and uncertainty. To avoid this, precise descriptive language and careful feedback and checking skills must be applied. The use of only verbal communication mimics the amount of time we typically spend on email, telephone or other communications media when we don’t share the same visual frame of reference, and the resulting misunderstanding and even conflict that can develop when a truly shared meaning is not developed.

The activity itself is simple:
Teams of 6 - 14 gather knowledge to identify 2 coloured abstract shapes that are missing from a complete set of 30. The communication processes involved are much more complex and take participants through increasingly sophisticated patterns of communication until the task is achieved.

Individuals draw on their experience and descriptive skills to explain to each other abstract shapes that they can hold in their hands, whilst blindfolded. They use feedback and clarification skills to ensure that their understanding is accurate.


Colourblind® was developed in 1991 when our colleague, Dr. Geoff Cox, designed and delivered the first week of an induction training programme for Air Traffic Control cadets. Each cadet facing an intensive, demanding training programme in which teamwork and communication skills would be fundamental to success. Each, ultimately, would accept professional responsibilities which allow absolutely no margin for communication error, misunderstanding or ambiguity.

Colourblind® enabled participants to rehearse every communication skill which Air Traffic Controllers need and to highlight the problems and pitfalls which communication breakdown inevitably brings when there is no visual common ground

Since 1991 Colourblind® has been used worldwide across languages, cultures and business backgrounds, to focus on the fundamental skills of great communication.

Colourblind is also part of our Education Sector Package for those who wish to use it with students or young people in an educational setting.
