What lens tint is best for flat light and overcast days?

For flat light and snow, reviewers generally favor lighter, higher-contrast tints (rose, yellow, persimmon) that boost terrain definition, while darker mirrored or polarized tints suit bright bluebird days. Many goggles in this category ship with two lenses to cover both ends. The product data here does not include independent VLT (visible light transmission) measurements, so check the listed lens spec before buying for a specific condition.
