    Hi, I am unable to change the alpha or color of my particles. I can create a new system and the very first thing I try to do is just set the color. No matter what I change it to, the particles stay white.

    The HDRP shaders don't use vertex color, which means they ignore particle colors.
    You can use the particle system HDRP shaders (packman -> HDRP -> extras).
    Or you can find some other shader/shadergraph that uses vertex colors, and then it should work.

    Sorry the support for particles in HDRP isn't wonderful :(

    Hey hey! this isn't exactly true. if anyone finds this thread, please don't get discouraged.

    you can expose a properly in the shader graph, and manually pass in the color yourself, like so:

    Using a Particles/Standard Unlit shader worked for me, to catch all colour changes including the particle Start Color and the Color over Lifetime settings.
