Hey All, what's the best way to avoid colour shift if you're wanting to put white on black? For example, putting the rain in on this picture. This is just an image pulled from Google as I was looking for a Punisher reference.

I tried putting a white high light over black the other day on a practice scribble and it immediately shifted.

when I work on a black surface I make sure to seal the black before I use any white over it , in most cases the surface is a tank that was already painted black and clear coated and this wont give you any trouble but if there is no protective layer over the black you can add a little orange to the white to prevent the paint shifting to bleu

Thanks for the tip. Do you know if intercoat would work if I used it to seal black paint before putting white over top?

From memory a little orange added to the white prevents the blue shift.
 
an inter coat will help and solve the problem depending on what inter coat is used it has to seal the black so it cant react with the white paint
 
There are many ways to go about this . If it is a panel piece adding a touch of Orange to the white will aid in the color shift to blue. Using a seal coat either with a seal coat , intercoat clear or clear coat. Or by a black panel.
On metal if black it the base coat I always suggest clear coating your base coat and scuff it where your are work is going to go. that does two thing one protect the base coat in the event something goes way wrong and you have to start over with the art. Two keeps the blue shift off the table in the first place.

That's great information thanks Herb. I have Trans base and 4030 Intercoat. Would either of those be a sufficient barrier or would it need to be a proper clear coat? I guess to protect the base coat if you needed to correct the graphics, it would need to be a proper clear.

The main thing is you want something that is not based the same as the protective coat. Trans base is just Wicked with out pigment, 4030 has been proven to allow color bleed which may cause a color shift. I have not tried the new 4040 yet which is suppose to be more of a true intercoat clear that will lock anything under it in.
For now I just use clear coat . Rattle can clear is fine for practice .
 
autobourne transparent sealer (6000) works well as a barrier on non candy 2.0 work.

Although thinking about it, i havent tried sealing the black then using white........
could be experimentation time this coming weekend

I've seen the Bleed Checker too, but haven't tried it. I have plenty of clear in rattle cans lying around, so I'll give that a whirl.

I've been thinking of laying down some black, masking sections and trying different products too. Could be an interesting little chemistry experiment LOL.

Being as I'm not able to offer a lot in the way of advice, this could be my way of contributing to the forum [emoji16].
I'm on board, I'll get to that in a couple of days.

Why not just buy a scratchbord that all ready has a coating of black ink on it. I have a few and I think I'll play around with them doing the white on black.
I'm not sure about the color shift that might occur. Will experiment some today with that idea.

That's another idea. I was mainly just thinking in advance. If for whatever reason I wanted to add white over black to highlight, but on a surface that can't be erased.

I look forward to see both experiments from you both.
 
I've just cracked the seal of my 4030 to give this a try. Damn this stuff it chunky, all I did was lift the seal under the cap so that I can put my filter on (small cut pice from a pair of tights / pantyhose) and I could see it. But then I hadn't shaken the bottle yet.
