دُهْمَةٌ

Blackness: (JK, S, Msb, K:) and a deep ash-colour [without any tinge of white: see أَدْهَمُ]. (ISd, TA.)

Also A brown ewe (نَعْجَةٌ حَمْرَاءُ): [see also دَهْمَاءُ, voce أَدْهَمُ:] and singular of دُهَمٌ signifying a certain sort [or breed] of sheep or goats. (JK. [But I do not find either of these two significations in any other lexicon.])
