I bought a gold bracelet. I took it out today and found that it was a bit red compared with others. Is it not good to have a good quality of gold or bought parallel imports?

it is good.
The golden redness may be caused by preventing too long in the sulfur environment or contact with acidic substances. When the gold appears red, it can be resolved by heating burning.
The gold content representation methods, such as thousands of gold, foot gold, 24K gold, etc., but there is no pure gold. This is because when the gold is extracted, the addition of impurities elements will not be avoided. Gold is prone to discoloration.
Call maintenance precautions
Golden jewelry gradually loses light due to sweat and other factors due to long -term wear. This is normal. In this case, customers need to return jewelry back to jewelry shops to solve them.
Golden jewelry should not be stored with silver jewelry, so as not to collide with each other and friction to make the surface of the foot gold jewelry become silver. The gold ring and the platinum ring are worn with each other, which can easily cause the two to rub each other, so that the surface of the gold ring is partially white with platinum hair.
Generally speaking, gold redness is good, indicating that the purity is high.

Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference.
