The following are all from Ron's list in post #1, but they don't have a colloquial name (if you know one, do share!). Copying here for searchability:

(Peak Absorbance 710nm) = 1,1'Diethyl-2,2'-dicarbocyanine Iodide

(Peak Absorbance 668nm) = 3-Ethyl-2-[5-(3-ethyl-2-benzothiazolinylidene)-1,3-pentadienyl]-benzothiazolium Iodide

(Peak Absorbance 522nm) = 1,1'-Diethyl-2,2'-cyanine Iodide [CAS #: 977-96-8], a.k.a. pseudocyanine iodide, pseudoisocyanine iodide

(Other) = 2',7'-Dichlorofluorescein or 9.(o-Carboxyphenyl)-2,7-dichloro-6-hydroxy-3H-xanthen-3-one Disodium Salt

(Other) = 5-(p-Dimethylaminobenzylidene) rhodanine [CAS# 536-17-4], EK catalog says rhodamine, but the internet would suggest otherwise...

I'm thinking that in addition to sensitizers, we've got a great list of baby names here...
