Fashion sense: 1. Gender stereotypes: 0.

Colours are finally in clear focus for a Toronto boy who has his purple glasses despite being told by an optician that bright colours are just for girls.

Kate Austin had taken her four-year-old son Lyle to look at glasses, "and he was immediately drawn to the bright colours," she told CBC's Metro Morning.

"He was all over the pinks and the purples," Austin said, as well as a floral pair.

But the optician told Lyle that those frames were only for girls.

"At that point I basically saw red and I tried to keep it together because I didn't want to draw too much attention," Austin said.

"But I did tell her that I thought it was the stupidest thing I'd ever heard."

Austin told the optician that there's no such thing as boy or girl colours.

"It's 2016, so I felt that it was bizarre that I'd have to say that," Austin said.

The optician wouldn't apologize, she said, but rather remained hostile while they were in the shop.

"I felt that it could have been a learning moment for her and instead it was just like hostility," Austin said. "I got a wave of hostility for sticking up for my kid."

Meanwhile, Lyle "just stuck to his choices" of frames.

"She kept pulling out blue and black and really sombre colours. I just felt like that is way out of line, and way out of date.

"It was just depressing to go back to the dark ages," Austin said. "But we are excited about his purple glasses."

Meanwhile, Metro Morning listeners tweeted their support for Lyle and his mother.
