Yes !!!
It still amazes me after having read about this on so many forums over the years that people are so surprised when they see a colour cast.
Having reread this I apologise if it seems a bit blunt.

I have seen this mentioned on this forum before.
Anyone know if it is purely a Cokin characteristic?

That's because supposidly Cokin can rectifid the colour cast issues so never ones are meant to be neutral.
There's still of the issue of some shops having old stock out back rather than new ones
Just spoken to Warehouse Express.
Apparently it's my cameras fault because it's digital and the sensor doesn't work well with these filters, especially at low light, i.e. dawn/dusk when there's a lot of red in the sky.
I suppose it's all in the description - notice the bit I've bolded.
"This ND plain filter reduces the amount of light reaching the film, but without affecting the colour balance. Suitable for a 3 stop Shutter speed/Aperture decrease."
I guess it's onto Cokin next then but all I can say is don't buy these filters for digital cameras.
Bit of a suprise though all of this because I did read the Cokin website that didn't make any mention of a colour cast. They have a specific section for digital cameras:

OK, so first weekend with playing with ND filters and I have a set of Cokin ones.
The thing is - they seem to leave a very noticeable warming colour cast effect, which has spoilt a few of my shots.
Is this normal?
I've contacted the uk distributor, who have passed on my comments to Cokin.
£75 down the drain though as they are useless really. Oh well.
what did you buy???

Yeah, these are the one to go for.
I never understand why folks buy Cokin... shows you the power of a brand folks have heard off.. even though strangely, comments are mostly negative

Really - what number cokin filter and what camera are you using?
From what I've read, it's not exactly a colour cast issue, if you define colour as the colours available in the visible light spectrum.
The issue (apparently, I haven't tested it myself) is that the Cokin filters transmit IR light more than visible light. Very long exposures will allow a much greater proportion of IR to visible light through, so the images are tinged with IR light, which the sensor will tend to render as red.
This is why some people have the issue and some people don't. Some cameras have stronger IR filters at the sensor than others, and it would appear that different batches from Cokin have different transmission properties.
I'll ask a mate who has access to all sorts of research equipment if he can test this for us. It'll probably be a couple of months before I find out though.
A120
A121M
Nikon D40
I used the A120 on film SLRs for many years.
According to Warehouse Express it doesn't affect film, just the cmos of digital cameras, the higher res ones more. I have A series filters (although not ND's) from my old film days, but they don't fit a 77mm lens
I bought the kit with the P121L NDx2 Filter, P121M NDx4 Filter, P121S NDx8 Filter and the P154 Grey ND8x
All come out badly purple
A good retailer/manufacturer would refund you if your new kit was not to your satisfaction, and the ghastly magenta cast you got from the Cokin filters is definitely unsatisfactory. I would insist!
When I got strange colour casts with a Lee filter a few years back they exchanged it no problem.
I don't buy the line about these filters being fine with film, but not digital. Though I could be wrong about that.
Anyway, who buys filters for film these days?
The option wasn't offered and to be honest I threw the plastic packaging away.
Hence why I've contacted cokin direct.
