Here is "Pretty Little Pink" from Leonard Roberts' book IN THE PINE - SELECTED KENTUCKY FOLKSONGS (1978). He says that "The song was sung and tape recorded in 1957 by Doris Breeding, Adair County, learned from her mother." (pp. 234-235)

PRETTY LITTLE PINK

My pretty little Pink, so fare you well,
You slighted me, but I wish you well;
If you on earth no more I see,
I couldn't treat you like you have me.

The fairest face and the neatest hands,
The fairest face and the neatest hands,
The fairest face and the neatest hands,
I love the ground where on she stands.

I would build my house on some mountain top.
I would build my house on some mountain top.
I would build my house on some mountain top.
Where the sun it failed to shine.

I will love you till the day I die,
I will love you till the day I die,
I will love you till the day I die,
To think of you it makes me cry.

The winter had broke and the leaves turned green,
The winter had broke and the leaves turned green,
The winter had broke and the leaves turned green,
And me, a poor boy, is going to be slain.

Come, my little Pink, come and see me die,
Come, my true love, come and see me die,
Come my dearest dea, come and see me die,
I will meet sweet Jesus in the sky.

And when you pass on by my grave,
So when you pass on by my grave,
And when you pass on by my grave,
You can view the green grass which over me waves.

I can't see any particular relationship between the tune that Leonard Roberts provides and the tune of the Lizzie Roberts version of "Black is the Color". But I am not trained to read music.
