The main thing to take away from this memo is that at least a portion of the paint formulas were developed at Navy Yard Philadelphia.

MEMORANDUM FOR FILE
Telephone Conversation between Lieutenant 0. R. Sutherland, U.S.N., Navy Yard Philadelphia and Daniel P. Graham, Senior Chemist, Bureau of Ships, with reference to Paints.
1. At approximately 1000 on 22 July Daniel P. Graham, Senior Chemist, in the absence of Lieut. Commander Ingram, U.S.N., called Lieutenant Sutherland in regard to several aspects of the low visibility painting program and inquired as to the progress being made on the welding tests involving zinc chromate primer. Mr. Graham stated that the Bureau was desirous of obtaining painted panels (about 12 in each shade) showing the results from adding the following amounts of tinting paste to five gallons of untinted white base, formula 5-U, (the tinting paste to be the same as the composite paste utilized in the production of "Sea Blue", formula 5-S and "Haze Gray", formula 5-H):
2 Pints made Haze Gray, ten pints made Sea Blue. Ocean Gray was 5 pints, so the 4 pints mentioned above would be lighter than Ocean Gray.
Lieutenant Sutherland was informed also that the Bureau was desirous of obtaining at an early date a 1-gallon sample of the white base formula 5-U and a sizable quantity of the tinting paste for such further experiments as might be performed satisfactorily at the Naval Research Laboratory. Lieutenant Sutherland promised to have these materials forwarded to the Bureau at an early date.
2. Lieutenant Sutherland stated that the welding tests on the zinc chromate primer would get underway within the next few days as the materials for the tests had all been assembled.
3. Lieutenant Sutherland stated also that he was sending a communication in regard to the production of a new deck paint and a suggestion for improvement in the plastic painting system to offset the tendency of the antifouling coating to sag from vertical surfaces if exposed to indirect rays of the sun.
