- When viewing a model, why do my solid surfaces appear black even though I have specified a different color?.
page There are two reasons why your surfaces may appear black. First of all, make sure that your graphics card supports 32 bit color and that this setting is selected. The other possibility is that you have the 'Emphasize Mag' option selected when you have no mode information. This option is on the 'Rendering' page of the 'Model View Control'.go source link
