Burnt Metal has a yellowish titanium sheen.
The temperature of jet exhaust gases is very high, and in most cases the paint cannot withstand such thermal loads. That is why the exhaust ports, and often the trim panels around them, on jet aircraft are left unpainted. Often these parts are made of titanium or stainless steel to avoid corrosion and rapid wear.
Titanium panels acquire a yellowish tint when heated strongly. This color, commonly referred to as burnt metal, can be seen, for example, on the nozzles of modern Pratt & Whitney engines installed on most modern US fighter jets.
Burnt Metal is made using an ultra-fine metallic pigment that will be the best choice for large-scale modeling.
Burnt Metal has a natural metallic sheen when applied. To avoid scratches and oxidation, it is recommended to cover painted surfaces with a layer of glossy or matte varnish
