Mmmm that elusive pink!
Around 2010 or so I spent a week trimming for this guy in Humboldt. He had spent the past 30 years or so developing this strain he called Stinky Pinky. Bright pink hairs like above^, but with THE MOST pungent Tangerine smell that would stay on your lips for hours. That was some of the best weed I have ever smoked in my life. Nothing I have found since has even come close. The mythical unicorn I'm chasing if you will.
Also, there is a guy near Seattle that has a strain called Pinkleberry with these pink pistils. Haven't tried it myself and I'm sure theres no Tangerine in it, but I love the color! PNW Roots is the breeder.
