Niagara: Bright Orange when using Particle Color

Hi, my particles gets a bright orange color when I try to use Particle Color node in Niagara. It looks correct when I use the preview Emitter. But it’s wrong in the viewport and in the Niagara System preview. If i use a material with a constant as color it looks correct. I have tried to restart Unreal.

The particle color only seems to work in the spawn particle for now.

For me it works as soon as I enable/disable the color module in particle update. Then the color gets updated everywhere.
