Interior green

[ScottsGT]

Ok, one has a more yellow hue to it, other is just green.  Is this one of those “I need to know my subject better” to pick which one to use?  Example, building the Fisher Cougar and soon Panther.  Going with gloss sea blue. Wheel wells are green but I cannot find color photos with enough detail online for reference.  

Was one used in certain years? Area of the plane? Manufacturers?

And why are both colors sold as “interior green” but one brand is green, another the yellow hue of green?

From what I have read, the major influence was the arena that they were deployed, also the year of manufacture played a major part. Availablility of resources to make the required paint had impact as well. I dont have a link to the article, but if you Google you will find it.
