If you're hoping to show confidence on a date, green may be the way to go, according to Lewis.
"This color is wonderfully symbolic of growth, stability, and a strong sense of self-identity," she told BI. Green can also signify a stable, calming presence, which may be of benefit to you on a date.
When it comes to choosing the right shade of green, Lewis recommended going for deeper hues. If the green is too light (think: pea soup), your date may feel ill at ease.
"You want to symbolize the good side of green for a first impression," she said.
