The glyph skinning feature allows you to fill the label image using a hue specified by the label's foreground color (the LabelControl.Appearance.ForeColor property). If the AllowGlyphSkinning property is set to Default or False, this feature is disabled.
For the best visual results, we recommend using grayscale icons with the glyph skinning feature. The DevExpress Image Gallery and Context-Dependent Images provides a set of grayscale icons, which can be used freely in your application.
