[Q] module to lock status bar color in lollipop

hello, is there a xposed module that can lock the color of the status bar in Lollipop
apps change it to red, blue,green, yellow, pink, purple...
i searched the repo but its only about changing color of status bar to match apps :|
i mostly set dark theme in apps... but some apps change the status bar color regardless... so i just want to not let apps change status bar color...
thanks..
