I have read of complaints in the St Blogosphere about the modern emphasis on resurrection at funerals. It was grounded in the bishops’ teaching at Vatican II:
The rite for the burial of the dead should express more clearly the paschal character of Christian death, and should correspond more closely to the circumstances and traditions found in various regions. This holds good also for the liturgical color to be used.
Currently in the US that liturgical color is nearly always white, rarely violet or black.
I find the cultural phenomenon of funeral wear to be interesting. Black remains a color less, I think, of mourning, and more of an automatic tradition, especially for marginal churchgoers. Hence the sight of some young women wearing dresses of the “little black” variety to funerals, in an attempt to blend in, color-wise.
A friend complained to me about it once. (As if I were going to write a Sunday bulletin missive that funeral visitors would actually read.) I suggested he let it go; they were probably just trying to fit in because “little” was the only black dress they had.
