Colour assign to geometry RGB?

Hello Guys,

I've sorted out my problem it was really simple. But I need now to know the exact colour assigned to the geometry. When o try to simulate the colour code (RGB) from GH in to Photoshop I do not obtain the same colour. (see image) What kind of output comes out of the gradien component (RGB, HSV?) I'm lost here.

Any ideas

thank you all in advance

Rhino doesen't apply the color directly. It depends on the lights of your scene. The actual color you see is a result of multiplying the dot product between the surfaces normal and the light source vector with the diffuse color. Even if you didn't add a light, there's always a default light. If you want constant color, use the emissive color input and set the diffuse color to black. You also have to make sure there is no ambient light adding to the color. The 'rendered' display mode usually has the ambient light to 0.

reply to me.

It was simple, the problem was the sorting list component that was changing the data ordering. By applying an interval (from the distance component) before the gradient component I'm able to retrieve the exact colour data for the panel fabrication

Thank you all...
