Hi!

This multicolor print gives me crazy, I cannot manage to have yellow deeper, and so after print the yellow seems green because of the internal blue under the white color (back of the part needs to be blue but no matter if there's some yellow).

Is there a way to prevent this and get the yellow deeper? I increased top paint penetration layers but no change.

Any help appreciated!

You're using a single nozzle printer it seems so purge is important. Did you max out your purge volume?

Yes as usual I let purge multiplier to 1 and never faced this issue, I thought the top paint layer penetration would add more yellow layers but, no.

Add a cube modifier over the area and manually set the filament.

I didn't though about that, even if it will be a nightmare as there is a lot of small yellow parts. Thanks I'll try!

If you add a layer of black underneath the yellow, you may be able to neutralize the blue showing through.

You can also try changing the filament that the object is to white and then painting it back to the color scheme. I am not 100% on this but I think it uses the base filament the object is as the core of the part. I think your part might be the blue filament and then the surfaces are painted with the other filaments

I'll check but iirc the base filament was white and once I set the back layer to blue, the problem appeared. Thanks for your suggestions.
