Help matching CSAO ballast color

[Engfanuk]

Hi guys, I could do with some help in matching ballast color for my 2007 CSAO south New Jersey proto-freelance layout.

I have some Arizona Rock CSX/Southern Pacific/Wabash ballast but I think it's too salt and pepper. To my eyes the target color is darker, more even with a slight blue tone.

Here is a very neat and tidy example photo of what I'm aiming for as a base -



However most of my track will be overgrown and less tidy -






I had planned on mixing Arizona Rock Earth with the ballast and applying static grass over that. But is till need the base ballast.

I'd like to stick with Arizona Rock products but it's a challenge to match colors without photos and even then it's different when applied on a layout than in a bag.

Can anyone help?

Warm regards,

Steve.
