'''Light Green SF yellowish''', or '''Light Green''', '''Acid Green''', '''Lissamine green SF''', '''Acid Green 5''', '''Food Green 2''', '''FD&C Green no. 2''', '''Green No. 205''', '''Acid Brilliant Green 5''', '''Pencil Green SF''', or '''C.I. 42095''', is a green ].

It usually comes as a disodium salt. Its maximum absorption is at 630 (422) nm.


'''Light green SF''', also called '''] 42095''',<ref name="Lillie, 1977" /> '''light green SF yellowish''',<ref name="Lillie, 1977" /> is a green ].
⚫ The dye is not very durable—it has a tendency to fade. When fading is to be avoided, it is replaced with ], which also has more brilliant color. Fast Green FCF can also substitute Light Green SF yellowish in many other procedures.


==Uses==
⚫ '''Lissamine green dye''' can be used to check the health of the anterior surfaces of the eye. It is available on a steret. The steret is wet with saline and then the dye is dropped into the lower fornix. The dye shows up conjunctival staining similar to rose bengal dye but it does not sting like rose bengal does.

===Food coloring===
Light green SF was once used as a green food colorant. Its use in the U.S. was discontinued due to its low popularity.<ref>{{cite journal|title=A Global Perspective on the History, Use, and Identification of Synthetic Food Dyes|author1=Sharma, Vinita|author2=McKone, Harold T.|author3=Markow, Peter G.|journal=Journal of Chemical Education|year=2011|volume=88|pages=24–28|doi=10.1021/ed100545v}}</ref>
