With the same disclaimer Johan gives about judging color, this appears to me to be the low-value color, flat plate printing (Scott 269 / Michel 309 A P a).
I should also note that in my 2015 Scott, their pricing of the rarer color is waaaaay out of whack. They price it at $1,500 MH and $$3,400 MNH. Michel catalogs it at €5 / €14, and it can be had on
ebay for €2-3.
