Linear Workflow & Blue Tint

[renantstein]

Hey guys,

So, I was aiming for the linear workflow to get 100% fidelity, but no matter what I try, the color white always seems to have this blue tint, with 10% (!!!) saturation.

Here's a print of the problem:

Hope you guys can help, thanks!

Do you have a sky with gray or white color?

[renantstein]

Nope.

Just the products and background, some standard lights and camera.

My environment is set to black.

Here's a before and after where I changed the saturation to zero on the camera imager (though I cannot use that when there's color). Just so you guys can see there's definetly some blue color coming from somewhere

Edit: So, ok, the problem are the lights. If I set my environment to pure white and let it iluminate my scene, I'll get white where it should be white (white materials). But if use any standard octane light, it gives me that blue tint, why is that? Shouldn't octane light be neutral at 6500k?

what's the color temperature on your lights?
can you upload your scene? you can swap the product with a cube if needed

If you color pick from anywhere in the liveviewer, you'll see it's not 100% white.

Thanks!

This is a common problem of Octane lights. Whatever temperature you have they are or too cold or too warm. Never neutral.

[renantstein]

Really? Geez...

Well, it's good to know at the very least.

Thanks Yan!

did you try color balancing the camera to the lights?
This is the same thing you have to do with a camera.

If you want neutral lights, you can switch from blackbody to texture emission.

Why not use the "White Point" setting in the octane settings? That is what I always do when I want to adjust the overall color cast of the whites. Just click on the color swatch, then choose a screen color in the live viewer with the eye dropper tool.
