Seven Years War Spain

My spanish army just starts to be built. It will consist of very few units, the needed figures I already have:

• Infantry battalion regiment Castilla (with battalion gun)
• Infantry battalion regiment Cordoba (with battalion gun)
• Brigade commander
• Artillery battery
• Artillery battery

Artillery ordnance colour (From Smoothbore ordnance Journal, www.napoleon.series.org.

The Spanish painted their ordnance in a blue grey and not as some authors think grey. The pigment was cobalt blue and when exposed to the weather for years it has a tendency to fade to a grey. The cobalt blue was derived from cobalt oxide mined in southern Spain that was sintered with silica (sand) at 1200 C. It was a very stable colour and was popular too in the Spanish Naval Regulations from 1772. The metalwork was painted black.
