Black Body Color
Colors
Black Body Color returns a color value of the light emitted by an ideal black body radiator. This can be used to calculate appropriate values for various color temperatures.
This node can convert color values in the range 1000 - 40000 Kelvin. Values outside this range are clamped.
The implementation in Resonite appears to use this table as a source of values. For values more granular than 100 Kelvin, the node interpolates linearly between the closest two values.
Inputs
Temperature (Float)
The temperature, in Kelvin, to calculate the resulting color for.
Outputs
* (Color)
The color value of the given color temperature.
