The Insights Discovery 4 Colour Model

The Insights Discovery model is based on the extensive research of Swiss psychologist Dr Carl G. Jung and the subsequent work of Dr Jolande Jacobi, one of his leading students.

In Psychological Types (1921) Jung’s typology was centred around the concept of different psychological ‘energies’ that influence how we behave, approach situations, and make sense of the world.

He identified three distinct sets of preferences that combine with different intensities to create our unique personal style – how we interact, communicate and work with others.

The Attitudes: The way we react to outer and inner experiences.

The Rational Functions: How we make decisions.

The Irrational Functions: How we take in and process information.

Carl Gustav Jung
Dr Carl G. Jung


The first two preferences are referred to as the attitudes, and describe our general orientation of interest with the external world of people and activities (Extraversion), or the internal world of thoughts and feelings (Introversion).

We all use both of these approaches to the world with varying intensities at different times, but most of us have an overall preference that we use most of the time.


The second pair of preferences determine how we make decisions and judge situations. These preferences are called the rational functions.

Thinking  is analytical and logical, with personal feelings put aside until an objective decision has been made.

Feeling  is subjective, based on personal values and the consideration of others affected by the decision.

Both are rational, judging processes and we all have the capacity to use both functions. However, we all have a preference: where we go to first in making our decisions.

Sensation establishes what is actually present, thinking enables us to recognise its meaning, feeling tells us its value, and intuition points to possibilities…

Carl G. Jung


Jung referred to the final pair of preferences as the irrational functions. This doesn’t mean illogical, simply more instinctive.

It’s how we perceive; the way we take in information.

Sensing  takes in information in bits and pieces, depends on all five senses and is clear and practical. It’s like building a jigsaw puzzle out of the here and now.

Intuition  is more future-oriented and conceptual, forming patterns to make new connections and possibilities. It’s that sixth-sense feeling that appears like a ‘hunch’ rising from the unconscious.


These different attitudes and functions operate around the dynamic tension of polar opposites.

If Thinking is dominant, then its corresponding opposite, Feeling, is automatically the inferior function.

It’s the interactions between these attitudes and functions that produce Jung’s psychological types.

Insights Discovery Polar Opposites

Insights Discovery translates this theory into a simple, accessible, and practical four colour model to understand an individual’s style:


Cool Blue – Introverted Thinking


Fiery Red – Extraverted Thinking


Earth Green – Introverted Feeling


Sunshine Yellow – Extraverted Thinking


All the colour energies have equal value, and everyone will use all four to varying degrees.

However, the sequence and intensity of our colour use are unique and determine our personal style.
