The Chromatic Universe
Colour Theory • Relationships • Light • Emotion • Culture
The Central Question
What is colour, how do colours relate to one another, and how can an artist control what the viewer feels, sees and understands through colour? Realm 05 moves beyond identifying colour to studying it as a complete psychological and physical system.
The Color Matrix
Ontology of Chromatic Relationships
Light & The Spectrum
- Colour as a visual experience born from light.
- Visible spectrum: Red, Orange, Yellow, Green, Blue, Violet.
- Core Distinction: Light Colour ≠ Pigment Colour.
Hue, Sat, Val & Chroma
- Hue: The basic colour family (Red, Blue).
- Value: Lightness or darkness (Light Blue vs Dark Blue).
- Saturation/Chroma: Intensity, purity, vivid vs muted.
Colour Models
- Additive (RGB): Light mixing; approaches White.
- Subtractive (CMYK): Pigment/Ink mixing; absorbs light to approach Black.
- Traditional (RYB): Historical painting model.
The Colour Wheel
- Primary: Foundational hues of a given system.
- Secondary: Combining two primary colours.
- Tertiary: Intermediate mixtures (e.g., Red-Orange).
Tint, Shade & Tone
- Tint: Colour + White (delicacy, atmosphere).
- Shade: Colour + Black (darkening, intensity change).
- Tone: Colour + Grey (neutralised, muted).
Temperature
- Warm: Reds, oranges, yellows (energy, intimacy).
- Cool: Greens, blues, violets (calm, distance).
- Temperature is relative to neighbouring colours.
Harmonies & Relationships
- Complementary: Opposites on wheel (visual vibration).
- Analogous: Neighbours (harmony, continuity).
- Triadic/Tetradic: Balanced complexity.
Simultaneous Contrast
- A colour appears different based on its surroundings.
- Afterimage: Perceptual effect after staring at a strong colour.
- Colour perception is dynamic, not purely physical.
Physical vs Optical Mixing
- Physical: Blending paint, pigment + binder on a palette.
- Optical: Small adjacent marks blending in the viewer's eye.
Layers & Glazing
- Opaque vs Translucent vs Transparent.
- Glazing, washes, layering, and scumbling.
- Observe how overlapping changes the final appearance.
Local & Reflected Light
- Local: Characteristic colour of an object (a red apple).
- Light: Illumination shifts the apparent colour.
- Reflected: Neighbouring surfaces bounce colour onto objects.
Colour & Hierarchy
- Dominance vs Secondary vs Accent.
- E.g., 70% Dominant / 20% Secondary / 10% Accent.
- A single contrasting colour can create a powerful focal point.
Emotion & Culture
- Associations: Joy, melancholy, danger, peace.
- Meanings vary drastically across different global cultures.
- Crucial: There is no universal one-to-one emotional law.
Colour in Disciplines
- Nature: Survival, camouflage, attraction.
- Architecture & Fashion: Identity, status, interior palettes.
- Cinema & Stage: Mood, character association, grading.
Digital Colour Systems
- RGB, HEX, HSL, HSV/HSB.
- Colour pickers, gradients, and blending modes.
Vision & Accessibility
- Human cone cells & Colour Constancy.
- Colour Vision Deficiencies (Red-Green, Blue-Yellow).
- Principle: Never use colour alone for critical info.
Palette Building
- Building 3, 5, and 7-colour palettes.
- Analyse for: Dominant, Accent, Warmest, Coolest.
- Grayscale translation & Emotional palette tests.
The Colour Story
- Master Project: Paint one narrative in 5 different systems (Warm, Cool, Mono, etc.).
- What changed even though the drawing stayed the same?
Realm 05 Doctrine
COLOUR IS NOT DECORATION.
COLOUR IS INFORMATION.
LIGHT CREATES THE CONDITION.
THE EYE RECEIVES. THE BRAIN INTERPRETS.
HUE IDENTIFIES. VALUE STRUCTURES.
SATURATION INTENSIFIES OR SOFTENS.
TEMPERATURE SHIFTS RELATIONSHIPS.
CONTRAST ATTRACTS. HARMONY CONNECTS.
CULTURE GIVES MEANING.
AND THE ARTIST CHOOSES.
