This article explains primary colors (red, green, blue in light; cyan, magenta, yellow in print), secondary colors formed by mixing two primary colors, and complementary colors, which are opposite each other on the color wheel and create strong color contrast. Tertiary colors result from mixing primary and secondary colors. Warm and cool colors influence the visual effect, with the orange-blue complementary pair being especially popular in photography and film.

Key Points in Brief
- Primary colors (basic colors) are the three colors from which all others can be mixed – in light: red, green, blue (RGB); in print: cyan, magenta, yellow (CMY)
- Secondary colors are created by mixing two primary colors (e.g., red + green = yellow)
- Complementary colors are opposite each other on the color wheel – together they produce the strongest color contrast
Explanation
The Color Wheel
The twelve-part color wheel arranges all colors in a circle that corresponds to the spectrum of rainbow colors. It consists of:
- 3 primary colors (additive RGB): red, green, blue
- 3 secondary colors: created by mixing two primary colors each
- 6 tertiary colors: created by mixing primary and secondary colors
Primary Colors
Primary colors cannot be mixed from other colors – they are the starting point for all color mixing.
| Color Model | Primary Colors | Application |
|---|---|---|
| Additive (Light/RGB) | Red, Green, Blue | Screens, cameras, monitors |
| Subtractive (Print/CMY) | Cyan, Magenta, Yellow | Printers, painting, printing |
Secondary Colors (Additive Model)
| Mix | Result |
|---|---|
| Red + Green | Yellow |
| Red + Blue | Magenta |
| Green + Blue | Cyan |
Complementary Colors
Complementary colors are directly opposite each other on the color wheel. Together in an image, they create the maximum color contrast – the eye perceives both colors as especially intense and vibrant.
The most important complementary pairs:
| Color 1 | Color 2 | Effect in the Image |
|---|---|---|
| Yellow | Blue/Violet | Classic, warm-cool, very harmonious |
| Red | Cyan | Intense, strongly contrasting |
| Green | Magenta | Vibrant, natural |
| Orange | Blue | The most popular complementary pair in film and photography |
| Red | Green | Very intense (also: Christmas colors) |
Note: Complementary colors do not have to be exactly opposite – “approximate” complementary pairs (e.g., red/green instead of red/cyan) also create strong contrast.
Tertiary Colors and the Color Triad
Tertiary colors result from mixing primary and secondary colors (e.g., yellow-green, blue-violet). They fill the gaps between the six main colors.
Color triad: Three colors evenly spaced on the color wheel (e.g., red, yellow, blue) also create strong contrast while maintaining balance – an advanced design technique.
Color tetrad: Four colors evenly spaced (e.g., red, yellow, green, blue) – even more varied but harder to manage.
Warm and Cool Colors
Regardless of primary/secondary classification, the distinction is made between:
| Warm Colors | Cool Colors |
|---|---|
| Red, orange, yellow, magenta, yellow-green | Green, turquoise, blue, violet |
| Feel warm, close, lively, inviting | Feel cool, distant, objective, calm |
In image composition: warm colors in the foreground + cool colors in the background → the eye interprets depth (→ color perspective, article 4.7)
Practical Tip
The orange/blue complementary pair is the most used in professional photography and film design – no coincidence. Sunsets (orange-golden light) against blue sky or water, warmly lit faces against a cool blue background: this pair is everywhere because it is instinctively perceived as harmonious yet dynamic. Those who use it consciously immediately give their images more depth.
