Fix emissive mesh color

com.unity.render-pipelines.high-definition/CHANGELOG.md

 - Fixed apply range attenuation option on punctual light
 - Fixed issue when using more than one volume mask texture with density volumes.
 - Fixed an error which prevented volumetric lighting from working if no density volumes with 3D textures were present.
+- Fixed issue with color temperature not take correctly into account with static lighting
 
 ### Added
 - Add option supportDitheringCrossFade on HDRP Asset to allow to remove shader variant during player build if needed
 - Add an option to generate an emissive mesh for area lights (currently rectangle light only). The mesh fits the size, intensity and color of the light.
 - Add an option to the HDRP asset to increase the resolution of volumetric lighting.
+- Add additional ligth unit support for punctual light (Lumens, Candela) and area lights (Lumens, Luminance)
 
 ### Changed
 - Re-enable shadow mask mode in debug view

-
-                    // If the light unit is in lumen, we need a convertion to get the good intensity value
