Which texture are you using to access the particle color?

I use vertex color.
I have found the solution.
In some case, color attribut in houdini is named Cd[x] Cd[y] Cd[z] instead of Cd[r] Cd[g] Cd[b].
There is no visual difference in houdini, but it seams to be important for the alembic export.

I have an other question about alembic import and particles.

Is it possible to import the particle size.
I tried psize for attribut name without succes.
