When fix kelvin temp in Corona lights?!

The selected value is not true at the moment. This problem is clearly ignored!

Was wondering about this too. Being able to set lights up to realistic temperatures would be really useful.

Could someone present some comparison presenting what they are getting and what is expected? I remember similar report from some time ago, but cannot find it right now.

That's my fault. Light sources in the corona renderer have the correct color temperature. But 6500, a white light source, can do a little light red, with some conditions. But what impact is not clear.

Reason why Corona's 6500K is not completely white:

The name D65 suggests that the correlated color temperature (CCT) should be 6500 K, while in truth it is closer to 6504 K. This discrepancy is due to the scientific community's revision of the constants in Planck's law after the definition of the illuminant.

I thought you're kidding, but decided to do quick test and apparently it's true. While i can see difference in comparison mode, there's no way i could tell difference in 3,6 K when looking at pictures separately. No way :]

if this is the problem, I will close this down

I've actually just started a new topic without realising this one existed but I'm having the same issue.

If I have a plane light set to 6500k and White Balance set to 6500k, the result is a magenta hue on the final image.

My thread topic is here with an example https://forum.corona-renderer.com/index.php?topic=20622.0
