Scale effect for the really small / large scales

I have read the note in this forum about aircraft scale, scale effects. I am hoping someone will be able to suggest values for ship scale percentages. I have wargame sized 1:2400 up to shelf hogging 1:350 scale ships. In a related question, is scale effect painting done to ships, or are they just weathered?

I believe scale effect applies to anything. I seem to recall that some people add 10% white to whatever colour paint they are painting the model. And I have also read that some people say it is all hogwash. LOL!

Maybe someone else has better info.

Found this:

Real colors and scale effect

Federal Standard codes given in the charts refer most often to the shade of the original color. Original color shades used on a small scale model will make it appear to dark, and have too much contrast. This phenomenon is commonly known as scale effect on color.

To avoid this, the shades should be lightened by mixing in a certain amount of white. Ian Huntley, a well-recognised authority within aero colors, arrived at the following guidelines (published in Scale Aircraft Modelling vol 5 nr 10):

Scale Add % of white
1/32 7%
1/48 10%
1/72 15%
1/144 23%

So the smaller the scale the more white you add. Of course it will get to the point where you add to much white and the “scale effect” is no longer valid and become ludicrous.

Thanks for the effort James. I had run into your list on an earlier search. I have seen, I don’t remember where, a chart / list / explination of mixing ratios that is if I may say so, the USA version. To the best of my recollection it was something like “divide the scale by 1/2 and this answer is the amount of white to add to the paint” for example (1/72 scale effect = 72 / 2 = 36 = 36% white added to full strength paint.). It may have been 1/4, or 1/8 or (pi R squared), but the ratio was used for all scales 1/24 - 1/144. The one here is not so linear.
