Looking for trousers

I’ve found trousers work well for me but I’m struggling with colors and materials. My favorite pair are from Sanctuary and I had them altered so they are pretty much perfect. They’re a rich navy shade. I’d like more but keep running into a few issues, mainly with color. The AF Sloane pants are fine but the colors all run a little more warm/brownish than I’d prefer. I go for cooler colors (I am a summer). The Favorite Daughter pants seem well reviewed but the fabric blend seems a little nutty for the price. I might just need to get over it.

Does anyone have a go-to spot for nice trousers in a wider variety of colors? Preferably with more natural fibers-though if I need to compromise on this for color I will.
