JNR "Grape" vs. Blue

[Szdfan]

I haven't been able to find an answer to this -- when did JNR start the transistion from the "grape" paint scheme on passenger equipment to blue? What's the blue paint called?

Transition began when SLs were phased out as the brown color was mainly used to prevent the coaches from looking too dirty.

So that would have been the late 60’s / early 70s?

According to JP Wikipedia, the shift in old type coaches from brown to blue was done in Showa 39/ Oct. 1964 for any new build or modernization of old type passenger cars.  Anytime after this point a mix of blue and brown was common, in the late 70s brown cars became much more rare as most of the fleet of older cars had been retired or overhauled.  The last known brown cars in service were three combine cars retired in 1986.

 

The shift to blue for JNR passenger cars probably came with the introduction of the first "blue train" 20 series sleeper express coaches, which were much more modern and comfortable than the older general service "old type" coaches.  When JNR began a large scale program of overhauling and modernizing its general service coach fleet they adopted the express color for the general service pool as well. 

 

Fun fact, the blue used was JNR Blue 15, which also was used on many other JNR engines and EMU trains as well.
