I just saw Eternal Sunshine of a Spotless Mind, and I was so inspired by Clementine's blue color. I would love to do something of the relatively same shade.
Buuut, I work at Egg Harbor Cafe. Which as the name suggests serves breakfast/brunch/lunch, so it tends to attract the elderly. They might not be so keen on seeing a blue-headed freak seating them down to their meal.
Any ideas? I'd love the color, but I don't know if I could do it and keep my job/pull it off.
I believe the issue would lie moreso in the opinions of your supervisor than the elderly folks. I work at Joann Fabrics and I got hired with Nuclear Red hair.. went through every other shade of the rainbow since I've been there and they don't say anything. (I'm thinking perhaps because their motto is "experience the creativity" so that would be pretty hypocritical.) But anyway. I deviate. There are really very few elderly customers who comment negatively on my hair. I've had about a bajillion old ladies tell me "my granddaughter has hair just like yours! It's so pretty and creative!"
(It's when they try to touch it that you've gotta look out. haha.) But if your supervisor/boss person doesn't want you going all-out blue you could do an under-layer dealy so that a ponytail would show the color off and leaving your hair down would cover it up for the most part. That's pretty much the only hideable way to do blue. at least that i can think of

Sowwy and good luck!
PS: Eternal sunshine is totally the reason I started dying my hair too! haha i forgot that's the reason I wanted to reply to you. I love that movie. OH and also if you're going in the blue direction I'd reccommend Special Effects Blue mayhem. From my experience it's the most vibrant blue around and it lasts the longest and best. It also will fade to purpleish. Not greenish yuck. (like Blue Haired Freak and most manic panic blues) and it won't start out innnncredddibly DARK like Blue Velvet (which is also pretty much impossible to get rid of too)
