Just to throw in my 2 cents... I've seen online, that 261s were yellow and some green.
Digging deeper, I saw some info concerning closest shade of green (the color I'm painting my 261). It is duplicolor's Detroit Diesel Alpine Green... available in rattle can at O'Reilly's Auto Parts.
I like it, and plan on painting the "Jobmaster" logo (in Yellow) on the Oil Cover... I didn't like the decal.
