Reads as warm and casual; a common budget or vintage-styled alternative to gold.
Develops a natural patina over time, which softens and darkens the warm tone.

No metal tone is objectively 'best' for any person — this is a description of typical visual effect, not a ranking.
The most reliable way to choose is to hold two metals against the same outfit or skin and compare directly, rather than following a fixed rule.
Understand your undertone before comparingCasual warm neutrals and earth tones commonly pair well.
Brass is copper alloyed with zinc, and the zinc content controls its colour. Copper on its own absorbs much of the blue and green; diluting it with zinc lets the alloy reflect more of the middle of the spectrum, so low-zinc brass looks reddish-gold and higher-zinc brass a paler, more silvery yellow. That lighter, less orange yellow is usually the easiest way to tell brass from gold side by side. Brass is also far more reactive than gold, so its surface colour rarely stays at the freshly polished state for long.
How it ages: Uncoated brass oxidises to a darker, browner patina, and in damp or sweaty conditions can form greenish copper compounds; lacquered brass stays bright until the lacquer wears.
