Render Engine set to Cycles.

For Meshes their diffuse colour is shown in 3d viewport when the Viewport Shading mode is set to Material. Curves do not do this, is there any way to turn this on for Curve objects too? For example below, the silver-grey tubes are Curves and I'd expect them to show the diffuse of the materials assigned to them (black, orange, and blue).

Renders like this, this is OK, and so is live Viewport rendering: enter image description here

The problem is Curves aren't showing their colour, instead a default grey. It doesn't matter which cycles shader-type is used. enter image description here

  • $\begingroup$ Works for me with cycles and BI, see: i.stack.imgur.com/WsrVM.png, maybe you overwrite the color with a viewport color? $\endgroup$

  • $\begingroup$ Whenever using nodes, viewport color is independent from Diffuse Color, to preview your color in the Material Preview, copy the value in the Viewport Color slot as shown above $\endgroup$

1 Answer 1



This appears to be fixed in recent builds,


I use Nodes for materials exclusively, and wasn't aware there was an independent Settings panel for the Viewport shading color.

1 and 2 are independent, and unlike Objects which are Meshes, the colour isn't automatic.

Here the spheres are Mesh based Objects.

here the blend

  • $\begingroup$ Since when has the color been automatic for mesh objects? $\endgroup$
