Colour Relationships

The way colours interact is key to understanding how to use them in photography.

Complementary Colours:

These are opposite each other on the colour wheel (e.g., red and green, blue and orange).

Effect: When placed together, complementary colours create high contrast and make each other stand out. This is useful when you want certain elements of your image to “pop” and grab attention.

Example: A photo of a red flower against a green background will create a striking contrast.

Analogous Colours:

These are next to each other on the colour wheel (e.g., blue, blue-green, and green).

Effect: Analogous colours create harmony and a sense of calm, as they blend more naturally.

Example: A landscape with shades of blue, green, and teal feels more cohesive and serene.

Triadic Colours:

These are three colours evenly spaced around the colour wheel (e.g., red, blue, and yellow).

Effect: Triadic colour schemes are vibrant and provide strong contrast while maintaining harmony.

Example: A photo of a beach scene with a yellow sandcastle, blue ocean, and red towel creates a lively but balanced composition.

Monochromatic Colours:

Definition: Monochromatic colour schemes use different shades, tints, and tones of a single colour.

Effect: This creates a cohesive, unified look and can evoke a sense of calm, simplicity, and elegance. However, too much of the same colour might appear flat, so adding variations in brightness and saturation can keep it interesting.

Example: A portrait photo in varying shades of blue, from light sky blue to deep navy, provides depth while maintaining a consistent mood.

Split-Complementary Colours:

Definition: This involves a base colour and the two colours adjacent to its complementary colour (e.g., red, yellow-green, and blue-green).

Effect: It offers contrast similar to complementary colours but with less tension, resulting in a more balanced image.

Example: A red flower with accents of blue-green leaves and a yellow-green background creates a pleasing contrast without the harshness of direct complementary colours.

Tetradic (Double-Complementary) Colours:

Definition: This scheme uses two complementary colour pairs (e.g., red, green, blue, and orange).

Effect: Tetradic colours offer a rich and diverse palette, adding variety and vibrancy to an image. Balancing these colours can be tricky, so often one colour is dominant while the others serve as accents.

Example: A photograph of a garden with red flowers, green leaves, blue sky, and orange sunlight creates a dynamic and colourful scene.

Warm and Cool Colours:

Definition: Warm colours (e.g., red, orange, yellow) evoke warmth and energy, while cool colours (e.g., blue, green, purple) convey calmness and tranquillity.

Effect: Mixing warm and cool colours can guide the viewer’s emotions and create visual interest through contrast.

Example: A sunset photo with warm orange hues in the sky and cool blue tones in the ocean contrasts warmth with calm.
