To the best of my knowledge, there is no agreed-upon action or figure that would satisfy those who deserve reparations. However, because newly-freed people were promised 40 acres and a mule, which we never received, I would suggest the current-day equivalent. To wit, a mostly paid-off home in the suburbs with a very large yard, and a paid-off SUV of one's choosing.

Next would be paid work sabbaticals for at least four year AT THE PREVAILING WAGE PAID TO WHITES and free college tuition. Cash settlements to the families of those who lost their lives, property, or businesses at the hands of white destroyers. Now THAT'S just a start. As for your other questions about color tests, I would suggest you look up the ridiculous rules by which people were still considered to be "colored." You'll see that it doesn't take much. You'll find those "rules" as silly as your question.
