Hey there,
i want to build a simple geometry pipeline inside grasshopper.
The input should be a color (RGB) and the script should output every object with the color.
Maybe someone got a quick solution!
Thanks!

I guess you’re looking for FindByDrawColor method:
private void RunScript(Color color, ref object A)
{
var objects = new List<GeometryBase>();
foreach(var obj in RhinoDocument.Objects.FindByDrawColor(color, false))
objects.Add(obj.Geometry);
A = objects;
}
from Rhino.RhinoDoc import ActiveDoc
a = []
for obj in ActiveDoc.Objects.FindByDrawColor(color, False):
a.append(obj.Geometry)
FindByDrawColor.gh (3.1 KB)
Although note that this will not update if an object in Rhino changes its colour. That plumbing is the heart of the Geometry Pipeline and it’s quite a lot of work to make sure you handle all the right events, but not too often and not when you’re not supposed to.
