Since my focus is now on colorful jewelry, does that mean I have turned my back on gold and silver for good?

No. The way I see it, silver and gold are colors too.

What I may have turned my back on are silver and gold jewelry that is plain and without other complementary colors.

Take this 925 silver slide with colorful inlay for example, whether on a silver neckwire or a leather cord, this slide brings color and interest to any plain necklace.
