There are also plenty of people in our world that fit that description better.
For what it's worth, the Hebrew word for brown/dark brown is Chum.
Read the bible some more. Read the book of Esther for example. Study up on history. Greeks and Romans were marrying hebrew women throughout their respective kingdoms. The disciple Timothy is the biproduct of a hebrew mother and greek father.
The hebrews were very much a mixed people.

Look at these protraits of Jews living in alexandria during the 1st century. Those aren't full blooded black folk fam.
I go by scripture description. The OG Hebrews were black, now what do they look like today? I don't know but I know those folks were black because the bible states that. That pic you posted is not how all black people look, especially if they are mixed with something. 'Miry Clay' is dark & muddy.
as for the red heifer pic you posted I can post more that look like the complexion of black folk.
I mean really the heifer is reddish-brown.
It's like some people like to ignore that fact for whatever reason. Mind boggling.
except none of those folks had woolly hair and didn't live in & out of Africa
