Postwar HMS Nelson paint scheme question

[Chango]

I am trying to determine if the top of the masts would have been white or RN light Grey:



I wonder about white because it appears the Vanguard was painted that way (RN Lt Grey, black, white):

... but the video is from 1960 and I need to stay accurate for the late 40's. Would I be accurate to use the Vanguard's color scheme (as seen in the video) with Nelson?

I would say, from the images I've looked at for the period Nelson had all black main mast throughout the war , whilst in 1937 the upper sections were white.
