Brown clothes?

My character is wearing a bee shirt and blue jeans, but the bee shirt has brown and dark brown stripes and the jeans are also brown. the character is also wearing the dripleaf hat and some flower vine gloves and a cape, but those look completely normal. I don't know how the shirt and jeans changed to brown, because I can't change the color of the shirt and jeans, and neither me or anyone in my family knows how to code, so it shouldn't be hacked. I'm not really complaining about it, I think it looks nice, but I'm curious about how it happened.
