White on rooster's ear lobe?!

[Redhead Rae]

Oh, Cool! I didn't know there were eggs darker than a Marans 9 on the scale. I have recently acquired a couple roosters and have been so into learning genetics!
So, those black chickens with white ears...they don't have the white egg gene then, do they? Therefore earlobes aren't always an egg-color indication?

Do you know what breed of black chicken?
Not the Ayam Cemani, right? ...they are pure black and lay cream colored eggs ... (I originally thought they laid black eggs, lol)

@ChickenCanoe Answered above. I couldn't remember the breed names. I've been considering getting Black Penedesenca eggs.

While generally true, white lobes = white eggs, red lobes = brown eggs. There are deviations from that rule not as well known in addition to what we discussed above.
Blue egg layers have red lobes.
Appenzellers lay white egg and have bluish lobes.
Silkies lay tinted eggs and have turquoise lobes.
Yokohamas lay a tinted egg and have white lobes
Redcaps lay white eggs and have red lobes.
Phoenix lay white to tinted eggs but with red lobes.
Naked necks lay a very light creamy egg yet red lobes.
The, now thought to be extinct, breed of Lamona laid white eggs and had red lobes.
Fayoumis, tinted eggs, white lobes.
Crevecoeur and Dorking, white eggs, red lobes.
Sabelpoots, Japanese bantams, Nankins, Old English Games, Modern Games white eggs, red lobes.
Sebrights and Sumatras lay white eggs and have purplish combs.

All Mediterranean breeds I'm aware of have white lobes.

And I had some mixed hens of EE x RC Brown Leghorn that had white lobes, but laid blue eggs.

When speaking of barnyard mixes, all bets are off.

Crested Cream Legbars have blueish white lobes and lay blue eggs.
