Which Hair Color Is Katy Perry's Favorite?

If there's one thing we've learned from celebrities, it's that hair color is the easiest way to change your entire look. And that couldn't be more true for mega pop star Katy Perry. She's gone from bright blue wigs to pink pin-up girl curls, sometimes all within one week (girl must use some really powerful hair conditioners). But among all of the hues, Katy Perry loved her green hair the most, according to People. And I have to say, I loved that look, too.

Colorful hair has been one of those trends that has followed us around for a few years. And if you're anything like me, you love it, but can't do it personally. Every time I think about how much I love the new lilac hair trends, I never think of them on myself. Not only have I never dyed my hair before – making it even harder to get it so light – I don't think I would be able to take myself seriously with purple hair. Fortunately, that's not the case for a lot of people, giving me a way to live vicariously through them. And as it seems, once you taste the rainbow, you never leave the rainbow. At least, that's how it for some celebs, Katy Perry being at the top of that list. She's been through all of the colors you can ever imagine – dark blue, pale pink, deep purple, platinum blonde – thus giving me life every time she reached for a dye bottle.

I try to figure out how Perry (and anyone else with bright colored hair) does it. I imagine the process is stressful, long, and maybe even a bit painful. And when I try to imagine doing it myself, I remember that Perry has a whole team of hair coloring experts and doesn't have to lift a finger.

And she's not alone. Tons of celebs have turned to the green color in the crayon box for their new hair inspiration. From Azealia Banks to Kylie Jenner, here are 5 celebs that have also loved going green.

1. Nicki Minaj

Like Perry, Minaj isn't afraid to dabble in the world of extreme hair colors. This green lob is a great blend of green and blonde, and I just love it so much.

2. Kylie Jenner

Jenner is another friend to the wild color world, and she usually does her colors in deeper versions of themselves. This ombre'd dark turquoise green was one of her subtler hues.

3. Hayley Williams

Instead of going full green, songstress Hayley Williams went with a mix of green and yellow. The moss-colored bob was a real change from her electric orange do, but it fit her angsty vibe.

4. Lady Gaga

Lady Gaga, much like Perry, has been through just about all of the hair colors there are. This teal-ish, seafoam green look isn't necessarily one of my favorites, but like anything she wears, she wears it with confidence.

5. Avril Lavigne

This punk rock princess tends to dabble in crazy color, rather than go full-on. These little green and pink highlights are an easy way to get some color into your look, without making your grandma gasp.
