This boxset homages the current IDW universe, which has Tracker being black. If the boxset homaged the 1980s universe(s), the toy would be white... but some people on the foreign fansites have an issue with the colour change, as if this toy is "wrong". They are not noticing or caring that this toy is actually accurate to the IDW comic universe, and if they have a problem with the colour change, they should have made a fuss in the comic news or reviews topics.

Reboots often do that these days, because of the over-white, over-male representation (with maybe a token black guy at the back and a female who often needs rescuing) of 20th century comics, cartoons and their associated toys.
As long as the story is good, and the character traits are the same or better), what difference does it make what colour or gender the main characters are (provided they don't make it a political issue or a plot device, which detracts from the integrity of the overall story arc).
