Yes, a 35% tint is darker than a 50% tint. Tint percentages indicate the amount of light that can pass through the tinted windows. In this case, a 35% tint allows only 35% of light to pass through, while a 50% tint allows 50% of light to pass through. Therefore, the 35% tint is darker because it allows less light to pass through compared to the 50% tint.
