Now I have some free time to explain.  
"FFR Powder" is probably a code for a colour/shade/tint powder used in achieving a desired colour. 
When I designed layouts for "4-colour" advertising, the client picked the shade from a chart with hundreds of tints.  Suffice it to say that the final colour would or could be a combination of the 4 basic colour powders. When I did a website, there were choices too. Paint your car, cannon carriage, house, etc. and the colour is drawn from these powders. 
I believe FFR Powder is in the class of misty light blue green?

  Nice for a steel gun carriage. 
I've been retired from it for quite a while. I may be incorrect. I probably am but this is what the question brings to mind. 
Many moons ago, I restored a classic 50s Benz and gave the hammer-head shop owner the colour. It was a deep burgundy with only a slight tint of red in the black.  I picked up the car before dawn outside his shop; drove to work; parked in the dark and went in. 
I came out at lunch time to admire my car. I walked the length of the block and it wasn't there. S.O.B.! Somebody stole it already.
Wrong!  The powder code letters used were not what I had picked. Instead, he painted the car Tobacco Brown; not Burgundy. I think he had dyslexia.  I sold the car. I liked my new 55 Chevy coupe better.
