What color was your skin before?

Assuming for now that your skin is normally pink-tan-white, then yellowish-ness can be a result of eating too many carrots or other orange vegetables, or it could be because of jaundice, meaning something is wrong in your body.

Jaundice most often makes the whites of your eyes turn yellow. If this is the case, see a doctor right now!

No

Beta-carotene does turn people orange, and there is beta-carotene in carrots. However, you would still have to eat a huge amount of carrots to turn orange, although if you were drinking a lot of carrot juice it becomes more achievable.

(These days beta-carotene is sold in capsule form for people wishing to have a year-round tan/orange glow).
