Hi all.....not an expert by any mean, but here arey my Two cents.
First thing to note: the colours used on that museum restoration are wrong.
That colour scheme, known as "Inmaculada Concepción", was common during the early sixties. It was used on CASA352, CASA2111 and Ha1112L. Fuselage was painted aluminium enamel, and undesurfaces were in light blue.
For the light blue, Humbrol 89 is an almost exact match.
By the way....the "Peugeot Blue" colour Legend behind the earlier "Buchones" Paint, is just that, a Legend.
That dark blue was actually a Hispano Aviación Factory applied colour, used on other aircraft such as the HA100 Triana or some prototypes. It resembled the colour of Comandante Comas' own Peugeot 203, but It wasn't an automotive Paint at all
