I have two sources that agree on the FS numbers for the green over gray scheme. The oldest is The IPMS/USA Quarterly, Vol. 16 No.4 - Summer 1981. Pg 178. Second is the recently released Caracal Models CD48219 B-26K Counter Invader decal sheet from 2022.
Dark Green is FS 14062.
Light Gray is FS 16492.
Looking at the Cybermodeler FS 595c paint cross reference we get these model paints:
Dark Green/Deep Green - Life Color 040.
Light Gray/Dawn Gray - Mr. Paint 362 or XtraColour X147.
Hope this helps.
