Material Color not changeable?

I made a copy of a material to create a new color needed. But as you can see from the attached, the color reamains a dark grey. The color of the object (not the material) is also set to the same yellow hue I want and it reads in the shaded mode. Why is the material so unintuitive?

I suspect the texture map. Try deleting that.

Thanks, I of course figured it out after I complained about it. It was a material downloaded from Food4Rhino and I mistook the texture for ‘texture’ rather than color.

I’ve also been getting an education in Blocks. But I’m encouraged a proper editor will show up in the next version.
