Window film technology
Neutral Tint
Neutral tint is window film with a flat, grey colour profile that does not shift the perceived colour of objects seen through the glass — preferred for accurate driving vision.
Neutral-tone films keep the spectral transmission flat across the visible band, so the world outside the cabin looks the same colour through the film as without. Less neutral films introduce a green, blue or warm cast.
For driving, neutral tint matters: traffic lights, brake lights and signage all rely on accurate colour perception. A film that shifts greens or reds can subtly impair recognition at distance.
Premium ceramic and multi-layer films like Platinum99 are engineered for neutral tone. Budget dyed films often shift warm or green and the shift can worsen as the dye ages.
