Light green is the standard dye in North American for staining collagen in contrast to acid fuchsin in Masson's trichrome. It is a component of Papanicolaou's EA series in conjunction with eosin Y and bismarck brown. It is also used extensively in plant histology. The dye's major drawback is that it fades. If it is important that fading be avoided it may be replaced with Fast green FCF, a closely related, but more brilliant, green dye.

Compare the formula to Fast green FCF and Guinee green B
