How to change task Bar Icons

[oppman]

Hello,

I am happy with the ROM I'm using but I would like to update the taskbar icons ( volume, bluetooth,battery, internet connection etc). The Current rom I have uses the White default ones but I have seen other roms with colorful ones. Im Using a 6.1 rom for Sprint.

I have search the forum and perhaps I'm calling it something else, So I cant find info Im referring to the bar on top where the START button is.

anyone can direct me to a post on how to change this?

Thanks
