Carrots
...Carrots. Hence the name.
Carotene is responsible for the orange colour of carrots. There are many other vegetables that contain Beta Carotene.
Oranges are orange because of a chemical called carotene, this is also responsible for the orange colour in, yes, you guessed it, CARROTS. Pumpkins and other orange fruit and vegetables owe there colour to carotene as well.
The three pigments that contribute to skin color are melanin, carotene, and hemoglobin. Melanin is the primary pigment responsible for determining skin color, while carotene and hemoglobin also play a role in influencing skin tone.

No. Carotene is the compound in grasses that gives both the yellow colour in the milk, and the yellowish colour in the fat of meat from grass-fed animals.
The pigment present in carrots that imparts their orange color is called beta-carotene. Beta-carotene is a type of carotenoid, which is a group of pigments that are responsible for the red, orange, and yellow colors found in many fruits and vegetables.
The best bet for a natural (IE no preservatives, no artificial flavours or colors) yellowish-red dye for food and fabric is *Beta Carotene*. This colouring agent is most commonly seen in carrots, and gives them their orange colour. The original colour of carrots was actually purple; beta carotene was added later to make them orange.
Carotene will fluoresce in UV light, but the "colour" of the fluorescence is infra red and cannot been seen by the human eye.
