Color Spaces in Resonance
Harmoniacum Method –
A Multisensory Framework for Colour, Space and Identity
The Harmoniacum Method understands colour, light and atmosphere not as direct biological agents, but as perception-based stimuli that modulate emotional and psychophysiological states via the nervous system.
The method is based on the assumption that needs and inner states structure perception and thereby guide the selection of colours, atmospheres, and qualities of resonance.
The Harmoniacum Method is a multisensory approach to the design of spaces, products and identity.
It integrates colour psychology, perception research, materiality, spatial dynamics and inner imagery into a coherent design process.
At its core lies the idea that spaces are not merely functional but resonate as inner images, values and emotional states.
The method translates these inner structures into colour, nuance, material, atmosphere and multisensory composition.
It is used within design & identity development and supports the creation of personal and organisational expression.
1. Foundations of the Harmoniacum Method
1.1 Multisensory perception
The effect does not occur at a cellular level, but at the level of integrated perception and central nervous system processing. Colour is not viewed in isolation but as an interaction between sight, sound, scent and emotional experience.The method synthesises these levels into one perceptual image to understand the overall spatial effect.
1.2 Psychological and emotional colour processing
Colour perception is always subjective, context-dependent and mediated by neuropsychological processes.
Colour decisions are influenced by biography, culture, the nervous system and inner imagery.
These individual resonances form the decision-making basis of the colour process.
1.3 Identity and spatial order
Spaces are understood as reflections of inner processes.
Colour makes identity visible and creates orientation, coherence and perceptual order.
2. Procedure of the Harmoniacum Method
2.1 Element Profile
The selection of an experiential cluster is understood as an expression of current inner regulatory needs, not as an objective measurement of them.
Each colour process begins with the definition of a foundational element (Fire, Water, Earth, Air).
These elements represent basic resonance qualities and are the starting point for colour selection.
2.2 Main Colour
2.3 Nuances and Modulations
Within the main colour, nuances, saturations and brightness levels are analysed.
The method identifies variations that create the strongest individual resonance.
2.4 Spatial Application
The final colour profile is translated into spatial components: walls, surfaces, lighting, material and atmosphere.
Optional scent and sound are integrated to achieve multisensory coherence.
3. Fields of Application
3.1 Organisations – Identity & Design
3.1 Organisations – Identity & Design
The Harmoniacum Method translates brand values and organisational identity into coherent colour and spatial language.
It supports:
-
development of identity-based interiors
-
emotional orientation for employees and customers
-
alignment between brand, perception and behaviour
-
environments that express identity beyond trends
3.2 Private spaces
Colour decisions support clarity, calm or reorientation in personal living environments.
3.3 Hospitality & boutique design
Hotels and retreats apply the method to create atmospheric spatial worlds with defined emotional impact.
3.4 Therapeutic and regenerative environments
The method is used where environments are intended to regulate or support the nervous system.
The application takes place within wellness, preventive and regenerative contexts and does not replace medical or therapeutic treatment.
4. Distinction from classical colour consulting
The Harmoniacum Method is not a style concept and not traditional colour consulting.
It differs by:
-
integration of inner imagery
-
multisensory resonance (colour, scent, sound)
-
structural coherence instead of decorative styling
-
individual rather than typological solutions
-
identity-driven orientation instead of trends
5. Scientific Context
The method is currently being prepared for external scientific review and accompaniment.
The method draws from insights across several fields:
-
colour psychology
-
environmental psychology
-
multisensory perception research
-
spatial & architectural psychology
-
human-centered design
-
neuroscience of perception
These disciplines explain how colour, light, material and multisensory stimuli shape orientation, wellbeing, identity and resonance.
6. Literature & Research Fields
-
environmental psychology
-
colour & nervous-system research
-
perception psychology
-
atmosphere theory (e.g., Gernot Böhme)
-
perceptual design theory
7. Summary
Harmoniacum is not a method of direct biological intervention, but a perception- and experience-based system for the conscious design of states, atmospheres and inner orientation.
The Harmoniacum Method is a structured process for developing individual colour worlds based on sensory resonance.
It connects perception, identity and design into a coherent language — applicable in interior design, architecture, brand identity, hospitality and therapeutic environments.
