Mine are yellow with a greenish cast to them. I've seen at least 3 different shades of yellow used over the years. Here is the data from the post war follow on specification that was adopted in 1951. Most of the stuff in it was a direct copy , with updated spec numbers. If you need the marking information, I can shoot some pic of mine this week.

MIL-C-5888 is the spec for the F-1 bottle and
MIL-C-5890 is for the G-1.

3.6 Exterior finish. The entire external surface shall be painted with one coat of primer conforming to TT-P1757,
and two coats of yellow lacquer conforming to TT-L-32. At the option of the contractor, one coat of enamel
conforming to TT-E-489 may be applied in lieu of the two coats of lacquer. The color of the lacquer or enamel
shall be gloss yellow in accordance with color number 13655 of FED-STD-595. Extreme caution shall be
exercised to prevent any contamination of the inside of oxygen cylinders during painting. Alternate paint systems
may be proposed to the procuring activity for consideration.

3.7 Identification of product. Decals, if used in lieu of paint, shall be approved by the procuring activity. The
cylinders shall be marked for identification in accordance with MIL-STD-130 and shall include the following
information:
Oxygen Cylinder, Nonshatterable
M5886/1-*
MIL-DTL-5886
Volume & Pressure (Maximum fill pressure in psi and Kg/cm2
)
Manufacturer's Part Number *
Contract Number *
Manufacturer's Name or Trademark *
Date of Manufacture
*The manufacturer shall include applicable information.
3.7.1 Additional marking. The cylinders shall be permanently and legibly marked on the neck, spud, wrench
flats, or fitting of the cylinder, in figures not less than 0.060 inch in height, with the date of manufacture or
hydrostatic test (month and year), such as 7-79, for July 1979. Each cylinder shall also be marked by painting or
decals in two places diametrically opposite each other with the following information: "BREATHING OXYGEN
AV". The height of the letters shall not be less than 0.375 inch and the color shall be a durable dull black. Paint
material used shall be as specified (see 3.7) and decals, if used in lieu of paint, shall be approved by the procuring
activity.
