It may be false. The reason for redness is the red copper of the electroplated plating. The silver is generally plated with red copper, and then gold is placed. The red copper is plated to cover the surface with fine flaws. Red copper is cheap, so it will not increase too much cost when plating! Gold is rarely plated red copper!
It golden gold often scrubs with toothpaste, so the brighter the more brighter.
