Mesh node color meaning
 

Hi everyone,
I am using ICEM CFD for meshing.
Why do my nodes have different colors in the mesh? I am not asking about the geometry - I have found a lot of information on the geometry topology but nothing on the mesh...
I have red, green, turquoise and black nodes (see attached pictures)... Also when switching to the node numbering display, the same color scheme applies to the node number.
Many thanks for your help.

Obviously that red are corner (or curve end) nodes, green - curve internal nodes. Black - surface nodes. Cyan - ? I don't have cyan in my meshes. I think Simon Pereira (PSYMM) could clarify this, but I don't know whether he appears on forum this days or not.

Thanks for confirming my interpretation of the red and green nodes :)
It'd be great if someone could confirm the black and cyan colors!
Most probably, the black ones are surface mesh nodes while cyan come from the transformation of quadratic (mid-side) nodes into linear ones...
