Front panel colours for HP gear?

[TERRA Operative]

I'm designing some additional labels for my HP6644A PSU that I am adding front panel binding posts to and I got to thinking, what the actual RGB or CMYK values for 80's/90's HP test gear is.

I have taken a photo of my panel to attempt to colour match from to try to account for yellowing, but it would be interesting (to me at least) to know what the actual colours used were.


Does anyone happen to know the answer?

You might try searching the trademark files.  Some companies have included specific color definitions in their trademark material.  Don't know if HP is one.
