The real colored silver won't fade, because the colored silver is an ornament made of silver with a content of more than 92.5% (the ear hook on the earring, the pin on the earring and the pin on the brooch are all 85% silver, in order to further increase its hardness and achieve a longer wearing period), then it is drawn by craftsmen and finally fired in a high-temperature furnace at 800℃ to achieve the effect of never fading. Unless, of course, what you buy is poorly made.

Although colored silver will not fade, it will also be oxidized. This is because the glaze on the surface of colored silver jewelry can't completely cover the silver tire, so the exposed place of silver edge is easy to be oxidized (silver is easy to be oxidized when it meets air, so colored silver jewelry should not be directly exposed to air as far as possible), and the oxidized silver edge will appear yellow and black.

Generally speaking, if you buy good colored silver, the appearance is not easy to fade, but it does not rule out that there will be some colored silver ornaments with poor workmanship on the market. So if you want to buy colored silver jewelry, you'd better go to a brand store, which also has after-sales service.
