Understanding color science helps designers and photographers achieve consistent, accurate, and impactful results. This guide explains 25 essential concepts in clear language, from the basics of light and pigment to practical challenges with screens, lighting, and fabrics.
Additive (RGB): Light is added to create color (screens).
Subtractive (CMYK): Pigments subtract light (prints).
Implication: Designs shift when moving between media.
Visible light is 380–740 nm. Shorter wavelengths = blue/violet; longer = red.
Practical Tip: Different light sources emphasize different wavelengths.
Measures the warmth or coolness of light.
Key Ranges: 2700K warm; 6500K daylight.
Tip: Match lighting for accurate color work.
Cameras need reference to render neutral colors correctly.
Tip: Use a gray card or custom WB.
Colors match under one light but not another.
Tip: Test under multiple lighting conditions.
Red, green, and blue light for screens.
Tip: Work in RGB for digital projects.
Cyan, magenta, yellow, and black pigments.
Tip: Convert files carefully for print.
Different media can’t reproduce all colors.
Tip: Design with the final medium in mind.
Chemicals that make whites appear brighter under UV.
Tip: Examine clothing under different lights.
Colors appear different based on surroundings.
Tip: Test palettes in context.
Eyes adjust to the dominant light color.
Tip: Take breaks when color matching.
Screens must be calibrated for accurate editing.
Tip: Calibrate monthly at 6500K.
Measures how accurately lights reveal color.
Tip: Use high CRI (90+) lights.
Brightness independent of hue.
Tip: Check designs in grayscale.
