What is "COSL - PANTONE"?

[Russ_G]

What is "COSL - PANTONE"?, I'm getting jobs with pantone colors named in the following way:

COSL - PANTONE 5555 M

Any ideas what this is, what book these are from or what the COSL stands for? Maybe this is a stupid question but it's new to me....

5555M is from the Matte Book...no idea what the COSL is.
unless it is a custom mix color.
5555 should be kind of a dirty minty green.

Thanks, I was just using 5555m for an example, they are naming all their pms colors that way, I thought maybe it was something new but more likely it's just something the designer is adding to to color name, no idea why, thanks again!

Not sure but I think that it might be something to do with Pantone Live. I know they add some kind of suffix to identify the printing method/substrate etc
