/*title_start*/Shaded and Unshaded Color/*title_end*/
/*text_start*/ZBrush is a paint program powered by a real-time rendering engine. In determining the appearance of each pixol painted on the canvas, ZBrush calculates many factors including color, material, pixol orientation, and lighting.

For this reason, the color applied to the canvas is not necessarily the precise color displayed in the \C020202Color\C484848 palette (or determined by the current \C020202texture\C484848). More likely, it's shaded by the other factors.

\C020202Shaded Color\C484848 refers to the colors that you see on the canvas after the rendering engine has factored in the material and other elements. \C020202Unshaded Color\C484848 refers to the color that is present without any rendering effects. To see the unshaded colors that are present on the canvas, turn on the \C020202Render>Flat\C484848 button.

\C020202Baking\C484848 a layer converts \C020202shaded\C484848 color to \C020202unshaded\C484848 color, retaining the appearance of shading and applying the \C020202Flat Color\C484848 material. 

When grabbing the canvas: the \C020202Texture>Grab Doc\C484848 button always grabs shaded colors (exactly what you see). The \C020202MRGBZGrabber\C484848 tool also has a modifier which determines whether shaded or unshaded colors are grabbed.

It's important to note that several of ZBrush's color-correction tools (such as \C020202Smudge\C484848, \C020202Shading Enhancer\C484848, \C020202Hue Shifter\C484848, etc.) affect the unshaded colors in the scene. As a result, you will sometimes see little effect from them unless you first bake the scene or activate the \C020202Render>Flat\C484848 button.
