Gray: It absorbs evenly for any color spectrum, so there will be no chromatic aberration in the scene, showing a real and natural feeling.
Brown: It can filter out a lot of blue light and improve the visual contrast and clarity. It works well in severe air pollution or foggy days.
Green: Because it can increase the green light reaching the eyes, it is comfortable and suitable for people who are prone to eye fatigue.
Blue-gray: Similar to gray, it can absorb any color spectrum uniformly. Because its color is darker, a visible light absorption rate will be higher.
Yellow: Yellow lens hardly reduces visible light but can increase contrast and provide more accurate vision, so they are often used in 'night vision goggles.' Of course, it is also only used for decoration nowadays.
Light blue, light pink, and other light colors: Light-colored lens is more decorative than practical.(https://www.koalaeye.com/blogs/our-stories)
