How can i view white wire in sculpt mode? I'm beginner in English and blender3d.

When i study sculpting of blender in youtube, there are white wires only in front-face of object in streamer's viewport like below picture.



But when i select wireframe of viewport shading in sculpt mode, there are orange wires besides back- face wires shown annoyed me like below picture.



How can I let view port shading be seen like youtube streamer?
Two things to do.


For the wireframe color, go to User Preferences > Themes > 3D View > Active Object colour.
In the "N" (shortcut) panel turn on Backface Culling under Shading tab to hide back part of your mesh.
