I haven't been glued to the discussions like I would have been back in the day, but I did jump in a bit more today because I saw some people arguing that RJ said in multiple interviews/signing reports that the Andorans were supposed to be English in ethnicity. And apparently not even the hardcore fans felt confident enough that they could prove that negative. I built the interview database, though, at least as far as research and data entry go - the only person who really helped me with that was my roommate - so I was pretty confident he'd never said that. He only said their accents were British/English. Anyway, I did some searches to verify that and chimed in, and I also dropped a bunch of quotes from the books. These two explicitly say the Two Rivers folk have dark skin, in RJ's first book, and his last:

Elaida had put down her knitting, Rand realized, and was studying him. She rose from her stool and slowly came down from the dais to stand before him. "From the Two Rivers?" she said. She reached a hand toward his head; he pulled away from her touch, and she let her hand drop. "With that red in his hair, and gray eyes? Two Rivers people are dark of hair and eye, and they seldom have such height." Her hand darted out to push back his coat sleeve, exposing lighter skin the sun had not reached so often. "Or such skin."

Tam was on the slope, now, and more Two Rivers men were pouring out of the fog with longbows in hand. Some tried to mingle with the men who had followed Perrin, to reunite with brothers, sons, nephews, friends, but Tam chivvied them away, trotting his black gelding up and down as he arranged them in three ever-expanding ranks to either side of the horsemen. Perrin spotted Hu Barran and his equally lanky brother Tad, the stablemen from the Winespring Inn, and square-faced Bar Dowtry, only a few years older than he himself was, who was making a name for himself as a cabinetmaker, and skinny Thad Torfinn, who seldom left his farm except to come into Emond's Field. Oren Dautry. lean and tall, stood between Jon Ayellin. who was hulking and bald, and Kev Barstere, who finally had gotten out from under his mother's thumb if he was here. There were Marwins and al'-Dais, al'Seens and Coles. Thanes and al'Caars and Crawes, men from every family he knew, men he did not recognize, from down to Deven Ride or up to Watch Hill or Taren Ferry, all grim-faced and burdened with pairs of bristling quivers and extra sheaves of arrows. And among them stood others, men with coppery skins, men with transparent veils across the lower half of their faces, fair-skinned men who just did not have the look of the Two Rivers.
There are a lot of generalized quotes about Two Rivers people being darker than the average Andoran, and Andorans being darker than the average Cairhienin, etc. I think it was headcanon for most people that African features were limited to Shara (Africa) and Seanchan (American melting pot), while Randland is some kind of rigid European parallel with plenty of dark-skinned races but nothing African. So it's a bit of a headcanon shift, but nothing too extreme.
There are a lot of quotes supporting diversity in skin color in the Two Rivers and in Andor, but I think skin-color diversity is not really what the controversy is about. It's about other African features, like facial features and hair texture, and also Aboriginal Australian features, which in the case of Madeleine Madden (Egwene) strike me as being closer to Indian than African stereotypes. Barney Harris (Mat) has a Mesopotamian look which seems a bit whitewashed in some of his headshots. It's a lot more obvious in his candid shots.
