The white shirts the team started with were replaced at half time with green shirts.
"Our boys couldn't make out who was who," said a more and more desperate Paul Sturrock
"West Brom were in white and black, it was a sunny day and they couldn't make out who was who.
"Players were unhappy about it so I wasn't not going to change it because I couldn't pick them out either.
"I struggled to see certain players myself.
"We have a problem with green seats (at Home Park).
"If someone comes to us in midweek games with blue on and we're wearing green it's very very difficult to see people over the other side of the pitch.
Jamie Mackie gave Argyle a 12th minute but by half time the game had swung Albion's way. Shelton Martis leveled before Marek Cech scored to make it 2 - 1 at half time.
Cech then completed the scoring in the 2nd half leaving Albion top and Sturrock under pressure.
