Frequently asked questions
How accurate is the conversion?
It uses the widely used Tanner Helland approximation, which is close enough for previews but is not a precise blackbody radiance calculation.
What do low and high values look like?
Lower temperatures around 2000 K look warm and orange, while higher ones near 10000 K look cool and bluish.
