Appreciated members,
I made a drawing using 3D solid modeling in which I assigned colors to the elements. The problem I have is that I can´t get a solid in white despite many tries I've done. If I assign 255,255,255 color (white) to a solid, it appears in light gray on the screen and when printed out in dark gray color, which has nothing to do with reality. Is it not possible to fix this without having to get in and render material assignment?
Thanks in advance.

Are you using the Truecolor tab to assign the color?

Yes, I am. I also have tryed in RGB and HSL models, and the result is the same: grey color.

I have tried the following actions:
1. Change the color of a solid´s face with "colored faces" to white (7).
2. Hatch a face of the solid with white (7).
3. Overlap a face with other identical face but in a different layer. Then assign color white (7).

In all three cases, the following happens:
The changed face appears black on the screen while on the printer preview appears in white. The problem is when you print it because the face is printed in black. In all cases the color I see on screen is the same that exit from the printer. And this is logical.
I also tried with different colors of floor and background sky, and this does not change the result.
I'm desperate with this. Any suggestions to get white solids?
I use AutoCAD 2016.
Thank you

I also have tried with “Wipeout” order but it does not work for a 3D solid respecting its edges in black.

The thing is with the rendered visual styles is they account for light scattering. Not all light reflects in the same direction from a flat surface, unless its a mirrored surface (and you won't get an object color then). Since some of the light doesn't get to the viewer/camera/viewport/etc. the brightness is decreased based on the angle to the viewing direction. You will only get a "pure white" when the surface is perfectly perpendicular to the viewing direction. Its only an approximation of reality, but is closer than an unadulterated color regardless of angle, and its how the graphics engine operates.

If you want flat, toon-ish shading, you might try fiddling with the settings of a custom visual style and materials properties. Otherwise you may need to print linework and use a graphics program to flood-fill with the exact colors you are looking for.
