• The geometric specifications for the union jack and the sizes and positioning of the stars are given in an attachment to Executive Order 10834 of 21 August 1959, printed in 3 CFR, 1959–1963 Comp., p. 368. Also see Commons:File:US Flag spec TIOH 5-1-17 1967.jpg, the specification drawing from the Army Institute of Heraldry.
• The official colors are part of the Standard Color Reference of America, specifically Cable Nos. 75001 (“White”)     , 70180 (“Old Glory Red”)     , and 70075 (“Old Glory Blue”)     . Colorimetric designations for these colors were precisely specified in a 1946 paper in JOSA. When the white point is taken to have the luminous reflectance of the flag’s white, these colors can be approximated on screen as     ,     , and     , respectively.
