Imron or Imron Equivalent Paints

[StinsonPilot]

I've got some work to do on my Stinson. It was repainted by the previous owner in 1982. He was kind enough to put the paint codes in the log books. But other than the White, can't find the other three paint colors.
I've looked on their website, which is Alalta these days, but the codes don't cross or even show up on any search.
What are my options?
The White shows it to be over $400 gal. At least I think it's a gallon, the only site I could find it doesn't really say.
Thanks...
