Once the quilt is done I doubt that anyone will spend time comparing the original with the quilt to see if you found the exact match.

Also, to make it easier, insteading of adding leading on top of the colors, have you thought of doing raw edge applique and leaving a bit of the black background showing between the pieces? The overall look is the same, and it's much easier.

Challenges are good, and I"m sure you'll get it done and it will be beautiful.
