Yellow for hospital ships funnel during WW1?

[aurélien wolff]

Hello, since I'm going to turn one of my 1/1200 scale titanic in a what if hospital ship and myabe do another mauretania as a hospital ship, I've been wondering what yellow should I use, some rendering of britannic show it with a more ocher like yellow while other have it brighter.

I think both revell 89 and SM 310 colors could work (?) and the britannic rigging plan has the funnels being painted "yellow".
Thanks for your answers, there seems to be some room to interpret the yellow.

It would be more realistic to use yellow ochre rather than bright yellow.

Recreating titanic and her sisters also show different interpretation of the yellow, so revell 89 would be closer.

or maybe you have to mix some of the paints

Colours are looking totally different on different scales - pure yellow is definitely too yellow
