I absolutely LOVE Aviva labs
solution .
http://avivalabs.com/ They have 8% (which I use primarily) 10% and 12% solutions, as well as booster drops. It's not the least bit orangey. They also have a
solution called Gimme Brown that is for your clients that already have a darker/warmer skintone, or those who just want to be really brown. If you call the toll free number the sales reps usually hook you up with some samples or send you out a variety pack for cheap. They're shipping is also lightening fast- I almost always get it in 24-48 hours at the most, and you can order by website which I love cause I usually think of it late at night. Good Luck!
