Suit Color Recommendations

Hey everyone, I’m getting elopement photos taken in August in the Banff National Park, Canada area. Does anyone have any suggestions for suit color that would look good with the surrounding area?

My fiancee doesn’t have a preference. She’s not told me her idea for her dress of course, but I have a sneaky suspicion it will have flowers incorporated into it somehow. Whether those will be colorful or white to match the dress is the question. We’ll be getting photos done with dramatic mountain scenery, the glacial lakes, pine trees, etc. We’ve briefly discussed a light brown or tan suit, but I wanted to know what others may suggest. Thanks in advance!
