John,
A silver/blue livery with the tricolor band on the tail seems really right to me. You may compare with the photos of “Safari II” on this page :

“Safari II” is said by Violette has wearing a cobalt blue/silver livery, and I would not be surprised that they kept the same colours.

It’s a very interesting photo of a plane I know very well, except that I had never seen any image.
“Safari III” is the DH built DH60M c/n 1443, registered F-AJKT. It’s the third DH60 owned by Jacques de Sibour and his wife Violette (Selfridge), and the first registered in France, evidently bought trough Morane.
F-AJKT was delivered to Jacques de Sibour at Stag Lane on January 31, 1930 and he flew immediately to Paris.
On February 3, they took off to Djibouti, via Italia, Tunis, Lybia, Egypt, Sudan, Italian Somali. They spent some time to Aden; after an unsuccessful attempt to fly to Sanaa, avoiding any dangerous experience, they prefer to fly back to Djibouti having an agreement to land at Addis-Ababa under one condition : to paint Ethiopian flags on the plane. They stayed one month in Ethiopia, Jacques flying for the Negus, launching tracts above rebel tribes. Finally, the Negus bought the plane. Used at the Ethiopien pilot school, it was damaged twice and captured in bad shape by Italien troops in 36.
A more detailed biography of Sibour and this full story (in French) is on my website :

The photo is probably taken at one of their halts in English bases : Heliopolis, Wadi Halfa, Khartoum or Aden. I would think Cairo or Khartoum (?) because the badges.
There is more than one badge on the plane : at least 2, probably 3. These souvenirs were also painted on Sibour’s Farman 291 “Safari IV”
The camel was painted at Cairo : it’s a Camel with a palmtree before the Pyramids. Probably tied in the RAF Base, but I haven’t been able to find the meaning until now.
A little lower on the left is a lightning, insignia of the 16a Squadriglia (Benghazi).
I think there might be a third on the left, maybe the 89a Squadriglia (Tripoli) : a white bird on a blue circle.
During its stay at Aden, the DH60 was marked with a winged 8 (N°8 Squadron)
I will put the images of these badges tomorrow.
