Yellowing water

I used Woodland Scenics’ “Realistic Water” over a painted plaster waterfall last year. The water has “yellowed” over time. Is there anything that can be done, other than paint over it?

How long ago did you poured it?
Did you try to remelt it with a heat gun or hair dryer?
I sent Woodland Scenics an e-mail asking if there was a way to restore to clear.
Here is there reply:

It it possible to remove it?

Wrong product - I was talking about “Realistic Water” which comes as a liquid. I’ve used “EZ water” before, too, and have not had the yellowing problem with it.

[D)][oops] I asked them again
Ok, here’s the real deal for sure!

That’s worth a try. What do you suggest to color the realsist water?

You can buy tinting pigment from a paint or art store. It should be water based.

I use to work as a color matcher, so I should have known to tint it with blue.
Adding blue to yellow makes green but don’t add too much or it’ll get too dark. Try doing it in layers of thinned out or transparent blue giving each layer time to dry to see if you like it.

How do we see color? White light is basically made of three primary colors, red, yellow , blue. If an object is yellow, it is because the white light strikes the pigment in the object and red and blue are absorbed by the pigment and yellow is reflected.

I would suggest using a very dark blue, or else adding in some black, to tint with. Yellow and black pigments, mixed together, usually come across as green to our eyes, and the extra darkness will add depth. Using straight blue bay end up producing a bright green which looks radioactive. You also might try drybrushing white highlights prior to applying the new gloss; the flat white will hide a bit of the yellow.
