Black moor are not born black. The young moors are actually colorless and will then slowly turn into bronze before coming to their all-black velvety appearance. Most black moors will retain the color until old age while some will slowly revert to orange color as it grows old. Believe me, I’ve seen before a young black moor raised up to become an orange adult telescope goldfish and many people do not realize that this is actually true.
