Temperature : Color temperature |
Red, Green, Blue : The color value of each property |
Set Temperature = Temperature \100 |
Calculate Red: |
If Temperature <= 66 Then Red = 255 |
Else Red = Temperature - 60 |
Red = 329.698727446 * (Red^-0.1332047592) |
If Red <0 Then Red = 0 |
If Red >255 Then Red = 255 |
End If |
Calculate Green: |
If Temperature <= 66 Then Green = Temperature |
Green = 99.4708025861 * Ln(Green)-161.1195681661 |
If Green <0 Then Green = 0 |
If Green >255 Then Green = 255 |
Else Green = Temperature - 60 |
Green = 288.1221695283 * (Green ^-0.0755148492) |
If Green <0 Then Green = 0 |
If Green >255 Then Green = 255 |
End If |
Calculate Blue: |
If Temperature >= 66 Then Blue = 255 |
Else |
If Temperature <= 19 Then Blue = 0 |
Else Blue = Temperature - 10 |
Blue = 138.5177312231 * Ln(Blue) - 305.0447927307 |
If Blue <0 Then Blue = 0 |
If Blue >255 Then Blue = 255 |
End If |
End If |
