rocker/air trumpet colour ?

[Kev]

Anyone know what the correct colour(if any) is used in the engine bay to paint the rocker covers and sometimes the air box trumpets.
If i remember correctly it's a sort of lightish grey'y green???

The air filters? are silver metallic but not too dark or shiny
The rocker covers are a mid grey solid colure - no green thats BMC for Morris Minors and old Minis' etc
