Dying brown before black?

[Jimmy McLaughlin]

Can anyone tell me why it is suggested to use a first coat of purple or brown when dying a piece of leather black ,instead of just dying two coats of black? Does it make a difference?

I have never heard that before but it would make sense that a primary coat of a dark but dissimilar color would produce a darker black than just black/black. 

In printing there is the term called “rich black” where one or more process colors are layed down before the black resulting in a deeper darker black.  (Ref: https://en.wikipedia.org/wiki/Rich_black)

I believe the process would be the same for leather dying.

I use dark or navy blue before I do black....

Never even thought about this. Will have to try it.

It works, I get an even deep black. I tried it with dark brown first. It seems that you get less rub off.

Is this dye type or method dependent?

So what would be the difference between that and just mixing some brown with the black? You're going to do two coats anyway. I sure like to see a couple of test pieces to see if I could tell the difference. Maybe I'll do that tomorrow.

I don’t think the type of dye matters. I read  the Al Stolman  book on color. I  tried it with the brown and black Fiebings oil dye.
