In that scenario whose home game is it? If it is ours, Melbourne are in the wrong but if it was theirs it is up to us to provide a kit that is suitable
Collingwood didn't make there jumper look more like Essendon's though. If they had red stripes I'd agree
In this scenario it is Melbourne's home game, but they have created a situation where two non-clashing guernsey's suddenly clash.
Also Collingwood did make their guernsey more like Essendon's. Their normal guernsey is about 70% black compared to Essendon's guernsey which is 90% black and Collingwood's new guernsey has only made them even more black, so they are perhaps up to 80%, making them more similar to Essendon in levels of blackness.
