Simple Explanation

When a speaker or device changes the sound slightly, adding its own "flavor" or tone to it.

Concise Technical Definition

Any deviation introduced by an audio component that alters the timbre, frequency response, or tonal balance of the original signal, resulting in a sound that differs from the source.

Layman-Friendly Analogy

Like looking at a photo with a color filter on it—it’s still the same picture, but now with a noticeable tint.

Industry Usage Summary

Commonly used in speaker reviews, mixing/mastering, and acoustic assessments. A "colored" system is not sonically neutral—it may enhance or emphasize certain frequencies (e.g., boosted bass or rolled-off highs). While sometimes desirable for creative or pleasing results, it is generally avoided in professional studio monitors or critical listening environments.

Engineering Shortcut

Coloration = signal altered by frequency response irregularities or harmonic distortion ≠ flat/neutral.

Full Technical Explanation

Coloration refers to any unintended or non-neutral alteration of audio playback caused by components such as speakers, cables, or signal processors. This can result from frequency response irregularities, phase issues, cabinet resonances, or even deliberate EQ tuning. It typically affects the timbre, making instruments or voices sound different from how they were recorded. Though coloration is often viewed negatively in technical circles, some consumers may prefer the warmer or brighter tones it can add.
