Thank you for reporting a bug to Unity. We have reviewed the issue carefully, and in this case, the team is unable to prioritize fixing this bug. There are a number of reasons we make this decision, including the impact and severity of the issue across our user and customer base, and the possibility that future plans may solve the problem in a different way, or that a workaround for the bug may be available. Today we will be closing this case. Thank you again for taking the time to report this issue, and please let us know if there is anything else that changes the impact or severity of this issue.

Steps to reproduce:
1. Create new Unity project
2. In Hierarchy window select Directional Light
3. In Inspector window > Emission > Temperature field enter NaN value
4. Observe the Scene and Game views

Actual results: Temperature field accepts NaN value, causing rendering artifacts appear in the Scene and Game view
Expected results: NaN value is rejected and reverted back to previous valid value, no rendering artifacts are visible in Scene or Game view

Reproducible with versions: 6000.0.73f1, 6000.3.14f1, 6000.4.4f1, 6000.5.0b5, 6000.6.0a3
