What is the "orange" in Orange Kush?

[stinkyattic]

Or it could be an orange strain (FD's Royal Orange, Aeric Cali-O, etc.) crossed to a Kush strain (OG, Pure, Hindu, Master, etc.)

This is a very good bet... there are plenty of strains that have 'orange' in the name due to either the color of the hairs (most strains DO have orangeish hairs at ripeness; some have much MORE hair and it gives the bud an orange look) or a distinct orange flavor, such as the infamous Orange Velvet, an elite strain that is currently being used as a breeder by TGA's MzJill, and a parent to her 'jillybean', which is supposed to have inherited the orange flavor from it.

The hairs on a bud are most often a pure white or very pale cream, but can also be brilliant red (I believe Stonehedge carries if not expresses this trait), varying shades of pink (for ex Stinky Pinky) or orangeish-yellow... however, when the hairs (pistils) dry up and shrivel at ripeness, they all just turn a browner shade of what they were.
