I have both ,Admiralty & Vallejo Yellow Ochre, but on test the Admiralty paint does not cover well, & needs 2 or 3 (or more) coats, whereas, Vallejo covers well in one, but allows for de-nibbing, before a second coat. Therefore, I'm going with that one for my Jokita Vic. When allowed to settle, in the bottle, Admiralty paint forms light red on the surface, & Vallejo forms a pale green. I recently threw out an old tube of Windsor Newton light terracotta, which looked very much like the 'yucky' new colour of Vic!!!Me too, that dirty pink turns a striking ship into a background piece. It seems to me that nothing ever stood still ship-wise, and yellow ochre was evidently the true colour for some of the time, and that’ll do for me.
I use Vallejo yellow ochre as I mostly only use Vallejo paints, but there never seems to be any material difference across brands and media, as I have various brands of acrylic tubes that yield the same hue. You can give it a bit more depth by washing with a dark brown artists ink, or (probably) just about any other wash medium that takes your fancy. You’ll see the un-inked ochre colour on my log, link below.
I should mention Admiralty Paints, which I think are sold by Cornwall Model Boats. They do a set of Victory colours. I have these from more than a decade ago and the YO had quite a nice, deep tone to it.
I combined 4 bottles of yellow ochre in a small jar to avoid any variation in shade.
