The first 2 blues were part of the first 7 'End of the Plain Plane' colours (8 if you include the abortive Lavender) introduced in 1965:
Sky Blue was worn by 6 aircraft and Original Dark Blue by at least 8 but both were replaced as new colours in the 1967 colour reshuffle.
In 1967 the Harper & George agency created 7 new shades for the Braniff fleet and both the original blues were replaced. The new colours were:
The Medium Blue was darker than the previous Sky Blue whilst the new Dark Blue was lighter than the original which makes determining which colour is which even more difficult. As with the greens the tinting of photographic film of the age sadly makes it very hard to see real reproductions of the colours in photos. The Medium Blue got onto at least 18 aircraft whilst the new Dark Blue was worn by 10.
In my collection I have four blue aircraft. The Aeroclassics Boeing 727-027C N7272 wears the Sky Blue - which is a bit too dark compared to the real thing. She switched to the H&G Medium Blue Jellybean colours before changing livery to the Blue / Light Blue Flying Colors scheme in the 1970s. Braniff utilised the plane for only 9 years before it was replaced by new 727-200s and sold to Transbrasil being re-registered PT-TYS. The plane was written off when it crashed on approach to Florianopolis on the 23rd April 1980.
My Aeroclassics Boeing 707-138B N108BN and Aeroclassics Boeing 707-320C N7103 are both supposed to be wearing the H&G Dark Blue colours. They certainly appear dark blue but actually bear a closer resemblance to the Original Dark Blue than the later H&G version. This is probably a result of the photo tinting issues fooling the manufacturer.
Lastly Aeroclassics Douglas DC-8-62 N1804 wears the H&G Medium Blue. My eyes aren't great at colour shades but the model does appear slightly lighter than the other pair but not light enough to really pass as the colour its supposed to represent.
