abnormal problem with graphic properties

[tonypezz]

Hello everyone, the problem is, that I should change color to individual surfaces, belonging to individual parts under a product.
is an operation that I always do, working in the context of the part, select the interested faces and change color, it always worked.
Now the problem is that each part, has its own color, and also working under the context of the single part, changing color to a face or spline that is, you change the color of the whole part.
I can't figure out what the problem is.
I hope I was clear..:smile:
solutions to the problem?

practically you had to set up both to the part that you have its geometric groups, in the graphic properties, under color/auto, to unlock the error, then return the color with the necessary one.:finger:
