Is the color of the slave or female slave offered as Ghurra a determining factor in its acceptance?

Primary text

The color of the Ghurra is not considered a factor in its validity. The ruling is based on the Prophet's (PBUH) judgment of a slave or female slave in the abstract, despite the prevalence of dark skin among the slaves of his time. Similar to livestock due as a penalty (diyah), the color is not stipulated for an animal required by law to be rendered as compensation.
