First pic
Utile would be the closest thing I've seen to that colour,
I only have two bits of the stuff, salvaged from a manure heap...
its darker than the rest of the dark tropical hardwoods which can have a yellow or reddish tones without going into browns.
Haven't a clue what the second is.
Iroko is in the third pic for sure, it is the most common you will be likely to find, if you're into hoarding reclaimed timber.
Nicknamed African teak by some, but real teak is from Burma, now Myanmar,
and Iroko comes from central Africa.
I have a shed full of the stuff from years of hording, it's great stuff.
