What is a good henna beard dye?

My beard is a dark red brown and my mustache/goatee area is a much lighter red/blond. I used a product called henna color lab: ginger blond to try and even out the color but it is still much lighter. The next darker color looks way darker than my beard. Anyone know of any other companies that might make something between the two?

The color I used:

The next darker color:

Other than my desire for an in between color I have no complaints with the product, it's actually pretty nice and forgiving on my pale, easily irritated skin.
