Get the shading color of the Material through API

[gprofile]

Is there a way to get the shading color of the Material through API?

Material Browser

Isn't that just the Material.Color property?

See here.

For me it always is, but my materials settings may be different from you.

Hi,

I looked up a material in RevitLoopUp and the shading color seems to be retrieved simply by:

Color c = material.Color;

string colorString = string.Format("Red [{0}]  Green [{1}]  Blue [{2}]", c.Red, c.Green, c.Blue)

Look here for more information about the Material class, at the bottom it has sample code on how to retrieve the other colors for cut and surface.

This link will have more information about the color class.

I hope this help!

Sincerely,

Sorry for not posting the code and making my intention not clear. I tried using property

Material.Color

It works but the materials imported from Rhino/SAT throws invalid or uninitialized color, below the working code for it

public void GetMaterialColor () {
	Document doc = this.ActiveUIDocument.Document;
	List<Element> materials = new FilteredElementCollector (doc).OfClass (typeof (Material)).ToList ();
	var message = new StringBuilder ();

	foreach (Material material in materials) {
		string name = material.Name;
		try {
			string red = material.Color.Red.ToString ();
			string green = material.Color.Green.ToString ();
			string blue = material.Color.Blue.ToString ();
			message.AppendLine (name + "-" + red + "_" + green + "_" + blue + ".");
		} catch (Exception e) {
			message.AppendLine (name + " - " + e.Message);
		}

	}
	TaskDialog.Show ("Materials in the project", message.ToString ());
}

How could I retrieve the RGB from this material?

Hi,

this may solve your problem:

Page 9 shows how to get/set the value.

@Revitalizer  Thanks for the link. It has in depth explanation about the materials. I tried to use this method to extract the color, but I see that according to API docs, the AppearanceAssetId returns invalid Id for the materials imported from external geometry.

ElementId appearanceAssetId = material.AppearanceAssetId;
AppearanceAssetElement assetElem = material.Document.GetElement(appearanceAssetId) as AppearanceAssetElement;

So I could not proceed further since the assetElem  will return null. Any thoughts on that or am I missing anything in between.
