This is the AFC yr to be the designated Home team. Which means they’ll probably be wearing dark. But asking to wear throw backs is not the same as asking to wear color rush, And most teams don’t have white as the color rush.
color rush isn't really a thing anymore... just some teams (like the Saints) liked their color rush uniforms and decided to keep them as "alternate uniforms"
throwbacks and color rush are treated the exact same nowaday... they are both "alternate uniforms" and are held to the NFL's "alternates can be worn 3 times a year" policy
the 49ers did get an exception to wear their throwbacks in week 17 at Seattle
