NiSi True Color Variable ND Review (2027)
In-depth review of the NiSi True Color Variable ND: colour shift control, hard stops, version range and skin tone performance.
NiSi True Color Variable ND
A variable ND engineered specifically to kill the yellow-green colour shift.
Our verdict
True Color is the variable ND for shooters who noticed the problem. Where rivals shift yellow-green as density climbs, NiSi's polariser design holds white balance with unusual discipline, and the hard stops keep you inside the honest range. It is a specialist's filter that makes a measurable difference on the most important subject in video: faces.
What we like
- True Color polariser design targets the classic variable ND colour shift
- Hard stops prevent rotating into X-cross territory
- Available in 1 to 5 and 5 to 9 stop versions for range precision
- NiSi's cinema-grade coating and flare control
What to watch out for
- Premium price for a focused 4-stop working range per version
- Two versions needed to cover the full density span
- Less ubiquitous at retail than PolarPro in some regions
What owners report: NiSi True Color Variable ND
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Skin tones stay believable, which is why colour-critical video shooters reach for it
- Hard stops keep the rotation out of cross-pattern territory during fast work
- Cinema-grade coatings control flare when shooting toward bright backgrounds
Common complaints
- Covering the full density span means buying the second version as well
- Each version working range is focused, so it is not a one-filter solution
- Retail availability is thinner than the biggest creator brands in some areas
Who it is for
Colour-critical videographers, wedding filmmakers and interview shooters for whom skin tone accuracy outranks all other filter specs.
The colour claim, examined
Variable NDs shift colour because their polarising foils are imperfectly neutral. NiSi's True Color design re-engineers the foil pairing to suppress the classic yellow-green drift, and comparative reviews consistently place it at or near the top for neutrality across the 1 to 5 stop range. White shirts and skin stay believable at densities where budget filters tint noticeably.
Range and stops
Two versions, 1 to 5 and 5 to 9 stops, mirror the PolarPro edition philosophy: narrower spans, cleaner optics, hard stops at the ends. The overlap at 5 stops is deliberate, giving a working density in both filters. Markings are clear and the rotation is damped like a lens focus ring, not a toy.
Build and coatings
NiSi's cinema filter heritage shows in coatings that shrug off flare in backlit work and clean without drama. The frame is slimmer than the PolarPro system and lacks its Defender case ecosystem, so budget a good filter pouch. Thread quality is excellent across sizes including the 95mm cinema-adjacent option.

Also consider
PolarPro Peter McKinnon Variable ND II
The premium variable ND with hard stops and a defender lens cap system.
Why consider it: The broader professional ecosystem and Defender protection if colour needs are standard-pro rather than extreme.
- Type: Variable ND, hard-stop editions
- Density: Edition 1: ND4 to ND32 (2 to 5 stops); Edition 2: ND64 to ND512 (6 to 9 stops)
B+W XS-Pro MRC Nano Variable ND
German variable ND with MRC Nano coatings and a slim brass frame.
Why consider it: B+W coating and brass frame discipline for photographers crossing into video.
- Type: Variable ND
- Density: ND2 to ND32, approx. 1 to 5 stops

Questions, answered
Is True Color shift-free at maximum density?
No variable ND is perfectly neutral at its limit, but True Color stays closest longest. Its hard stops define a working range that is honest in practice, not just in brochures.
Which version for wedding films?
The 1 to 5 stop version covers ceremonies and receptions near windows. Add the 5 to 9 for harsh midday exteriors and beach or desert venues.
Can I stack it with a polariser?
Variable NDs already contain polarising layers, so an added CPL interacts unpredictably and can create banding on skies. Use the variable alone and rotate the whole filter for polarising effect on water and glass instead.
