Reddish royal blue
P.W. Akkerman #00 Royal Akkermanblauw is a royal blue with the usual red component of such labelled colours in the likes of Kaweco Royal Blue, Montblanc Royal Blue, Diamine Sapphire Blue, and, to some extent, J. Herbin Éclat de Saphir (which is bluer). Heavy red sheen is present in highly saturated areas, as well as when using a fine Japanese nib. The way this ink sheens reminds me of P.W. Akkerman Shocking Blue, Diamine Majestic Blue and Bilberry. The ink does behave flawlessly in all my nib and paper combos, no complaints from me on its performance; I’m just not a fan of inks presenting this level of sheen. I much more prefer Kaweco Royal Blue with its contained red sheen.
