The above is true, but my opinion is that with carbon steel you let the patina develop because it shows character and useIf you want shiny blades then go for stainless steel!
If all you do is keep them in the tubes, unused except to inspect them, then they should remain pristine. Handling them and wiping away the oil will expose them to the elements, and you might get pepper spots or tarnish, or even rust if you're neglectful. Using them will bring the patina. Cut dry stuff and keep it oiled and it'll stay shiny longer. Leave off the oil, and it'll darken. Cut stuff like meat or fruit, it'll likely patina instantly if it's unprotected (ie: wiped clean so you don't taste oil).
It really depends on what you use, or don't use them for. Keep in mind that many of use like patina. An honestly earned patina gives the knife character and makes it "yours", possibly with stories to tell. A forced patina (sticking it in an apple or potato or otherwise purposely using it for things that will cause tarnish) can have the same effect, just quicker. If you really want to use the knife but keep it pristine, you can, but as others have said, just go with a stainless knife.
I don't like the looks of a patina on my own knives. I occasionally carry and user a GEC with 1095 steel. Same with Case CV. Unless I cut food with them, they don't develop a noticeable patina. I do put a drop of mineral oil in the pivot once in a while and rub the excess onto the blades before wiping them off.
A lot of the knives you see with dark patinas are the result of people intentionally creating them because they like the way it looks.
