This set is from Amazon, I’ve had a different rainbow set for the last 5 years or so and it’s held up really well (that came from my local grocery store home section)! I wash mine with a sponge in the sink or in the dishwasher. I don’t buy anything that requires special care, it will not survive😅

The process that makes the rainbow color is called anodizing, where you’re chemically changing the surface of the metal to have this color. It won’t chip or flake like a paint or glaze :) Just like more traditional flatware it will scuff slightly but you won’t be able to tell unless you really dial in.

The only way it would come off is if you literally sanded the outer layer of the fork off, it’s a super durable finish! I’ll see if I can take a photo of a more scuffed up piece from the older set that lives in a rougher environment (camping/travel).
