Cannot get the correct vertex color from Vertex color on color ramp

Hi, I am trying to set a unique color for my generated objects on a spline,

tried to set all objects to the same color and as you can see we are still around 0.25 in the fac in the colorramp :s

(sorry for the image could only upload 1 image)

hey,

you might want to post that in support, not coding, that’s not actual code
