There are 33 colors.

"*Some awesome MultiColore tips submitted by orchids13:
"One of the best ways to distinguish the real ones from fake ones is to familiarize yourself with the 33 colors on the MC bag...the order of the colors is always the same for each ROW of LVs, although different rows appear on different bags so that each bag may not have the same exact order or colors showing on the face.
Here are the main color schemes for the LV rows on the white Multicolor items. All appear on a continous line:
1) Fuschia, Hunter Green, & Black
2) Mustard yellow, berry pink, and royal purple
3) Navy blue, chartreuse yellow, and turquoise/aqua
The little pocket on the outside of the MC Speedy may disrupt this flow since it's a new piece of material that makes up the pocket, but the two colors on the pocket will always fit in with this flow (i.e., bright pink will exist with either green or black)."
