as noted in android 5.0 behavior changes of android developers site under notifications:

notifications drawn dark text atop white (or light) backgrounds match new material design widgets. make sure notifications right new color scheme. if notifications wrong, fix them:

use setcolor() set accent color in circle behind icon image. update or remove assets involve color. system ignores non-alpha channels in action icons , in main notification icon. should assume these icons alpha-only. system draws notification icons in white , action icons in dark gray.
