Staining Blackbutt pergola

[Clayman]

Hi all,
I am building a Blackbutt pergola with Spotted Gum decking. As the Spotted Gum is a little browner than the Blackbutt, which would be the best stain to make it a bit browner?

Intergrain NaturalStain comes in sample pots so you could test the best match.
