My Flashcards

Definition

Meaning

A color created by mixing different wavelengths of light, where combining all primary colors (red, green, blue) produces white light.

The principle or system of creating colors by adding together light of different wavelengths, used in digital displays, photography, and stage lighting.

Linguistics

Semantic Notes

Primarily used in physics, photography, digital media, and color theory. Contrasts with 'subtractive color' (used in printing/painting where mixing pigments absorbs/removes wavelengths).

Dialectal Variation

British vs American Usage

Differences

British English occasionally uses 'additive colour' (with 'u'), but the technical term is identical in both variants.

Connotations

No significant connotative differences; purely technical term in both regions.

Frequency

Equally low-frequency in both variants, confined to specialized technical contexts.

Examples

By Part of Speech

verb

British English

  • The system additively colours the image.
  • We need to additive-colour mix these lights.

American English

  • The software additively colors the display.
  • They additive-color blended the projections.

adverb

British English

  • The lights were mixed additively to produce white.
  • The colours combine additively on screen.

American English

  • The projectors blend colors additively.
  • It works additively, not with pigments.

adjective

British English

  • The additive colour process is essential for digital cinema.
  • We studied additive colour mixing in physics.

American English

  • The additive color system is used in all LED screens.
  • Additive color theory differs from pigment mixing.

Examples

By CEFR Level

A2
  • Computer screens use additive color.
  • Red, green and blue lights make additive color.
B1
  • Additive color mixing creates white light from red, green and blue.
  • Your TV uses an additive color system to show pictures.
B2
  • Unlike painting, digital displays rely on additive color principles where light emissions combine.
  • The photographer explained how additive color differs from the subtractive process in printing.
C1
  • The additive color model, predicated on the trichromatic theory of vision, underpins all emissive display technologies.
  • Critically, additive color synthesis involves the superposition of spectral power distributions, not the absorption of wavelengths.

Learning

Memory Aids

Mnemonic

ADDitive color ADDs light (like your phone screen ADDs red, green, and blue light to make white).

Conceptual Metaphor

COLOR IS A SUM (mathematical addition of light components).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating as 'добавочный цвет' (incorrect). Correct: 'аддитивный цвет' or 'цвет аддитивного смешения'.
  • Do not confuse with 'аддитивная цветовая модель' (additive color model) – the same concept.

Common Mistakes

  • Using 'additive color' to refer to paint mixing (which is subtractive).
  • Pronouncing 'additive' with stress on second syllable (should be first: AD-ditive).
  • Writing as one word: 'additivecolor'.

Subtractive color, used in printing and painting with pigments (CMYK).

Because you are adding together all visible wavelengths of light, which our eyes perceive as white.
