HosekWilkie Sun color issue

[SSmolak]

Adding D65 white light spectrum was great idea to get rid of blue tint from sky and HDR maps but I thing that it was done too much and we have problem from another way. Many people noticed that there is problem with too much warm color from this new Sky model using D65.

Please try simple scene with plane and box all materials grey. Sun generate yellow, warm cast color, too warm colors even if it set to above 45degree from horizon.

In natural Sun has pure white color. This warm color is only from atmosphere, Sky only if sun is near horizon.

At the moment we have problem because asphalt, pavement that is directly light by Sun have too warm colors. Black asphalt is going to be yellow especially in specular channel. Under balconies we have yellow tint.

I did some test in Photoshop and reducing warm color from Sun like 25% works very well.

Hi,

Did you try the Camera Imager's White Point?
Worth mentioning that it gets applied to linear scene-referred OpenEXR files and may be a solution for you.

Thank you for mentioning this option. White point is the solution especially in Kelvin Temperatures mode. I have fully calibrated monitor using Spyder 5 and in my scene and eye 5800-6000K generate pure white Sun color. So there is little color shift by default from 6500K. This is the same what I did in Photoshop.
