Active colours not showing on iOs

Hi, I’m very new with the whole dashboard thing, but I’ve been playing with a simple dash on my old 1st gen iPad Mini. I’ve created a few tiles with custom active colours, and these work fine when viewing on my laptop, or on my iPhone, but not on the older iPad. Is this likely an age thing on the iPad? Its as up to date as I can get it, but its certainly a few versions back.

This isn’t a deal breaker for me, just curious if there was something that I missed is all.
