Men are usually terrified of bright colours because they might seem intimidating to match, leading them to opt for safe, muted colours. (Boring.)
Black and navy are two hues men feel most comfortable with. Yet, other deeper tones, such as khakis, can also be a great alternative to expand your wardrobe with. Go for military green, greys and chocolate brown, these are the palettes of subtle khakis that are not conspicuous, yet a great way to refresh your closets.
