How to dye my blue trousers darker?

Basically I have a pair of blue trousers, they're a deep blue, but they're brighter than I'd like. I essentially want to dye them a dark blue, closer to navy, but every article I find or video is about dyeing jeans and I don't know if it works the same. Can anyone give me some tips?
