Green hair color is rich and vibrant. Some shades are reminiscent of bubbling sea foam, while others resemble a pine forest after a spring shower. But there’s still no way to tell how each shade of green will wash out. They can fade to blue or even take on pink undertones.

Professional hairstylist and vivid color specialist Kate Harrison understands her clients’ frustration when they can’t find their perfect shade of green. “One thing I’ve learned as a vivid stylist is that NO brand makes a good deep green color. So if you can’t buy it, make it yourself,” the hair pro explains in her Instagram video, sharing her own deep forest green formula that transforms her client into a fairy queen.

Kate Harrison’s deep emerald is a combination of dark blue, teal and yellow. The hairstylist admits that it took her a while to find the right shade of green to create a lived-in dimension and magnetizing depth. “I’ve found that creating my own colors from a more primary color base gives me a richer color than using something straight from the tube,” the hair colorist explains.

Her experimentation with different shades and colors helps her create a go-to formula that works for blonde and brunette hair. For those looking to deepen the color even further, adding a touch of purple to the emerald formula works just fine. This shade of green is becoming a sensation, causing the comments section to explode with praise. “Ugh, I’m drooling over this color,” one person wrote. “This might be my next color,” another follower noted.
