I recently had to do a little research on matching paint for a military
aircraft comparing US Navy Haxe Gray to a UK aircraft color called "Sea
Gray". According to 2 US (Sherwin Williams, and Cortaulds who is really
Canadian) and 1 UK (name is forgotten) paint manufacturer, even if you have
a manufacturer color number, the actual shade, tint and hue will vary
according to which plant the paint is actually formulated at. This is
because even though the chemical/mineral ingredients are specified by the
formula, the actual components (like the pigments) can vary depending on
where they were mined, etc. So, they said in order to get an accurate match,
you really have to have a sample of what you want and then they can color
match it by computer. This is even true if you specify paint color by a
"national standard" such as FED-STD-595 which is the US Gov't paint standard
for all colors procured for anything for the government.
