Fueling & Injection - injector color = size?

i've searched and i cant find anything on here. or anywhere else for that matter.

bosch/ford injectors are color-coded, right?? anyone have a chart?

i have some blue ford old-style fat injectors that we thought were 42's, but looking on ebay, all of the similar 42's are lime green. any enlightenment?

light blue (like carolina blue) were usually 24's... I think 30's are red..... and the 42's being green sounds right..... My bosch 30s were red and the bosch 24's were blue...

sounds like green are the 42's....
