Graph color change not being reflected


I’ve been setting up dashboards for my organization to have simple monitoring of devices. But I’d like to change around the color the graph data. I’ve added the following line to my config.php, but I’ve yet to see the color change appear in libre.

$config['graph_colours']['mixed']  = array("05ff19", "008C00", "4096EE", "73880A", "D01F3C", "36393D", "FF0084");

So I’m just wondering if I need to restart anything or how I go about this. I’ve replaced the red from CC0000 to a neon green 05ff19. But in my graphs I still see red.

Thanks in advance!
