### Property Value
 [ColorManagementEngine](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_ColorManagementEngine.htm.md) value specifying color management engine.
 
## Remarks
  
Color management is enabled if all of these conditions are met:
 
1. This property is set to [LittleCms](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_ColorManagementEngine.htm.md) or [AdobeCmm](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_ColorManagementEngine.htm.md).
2. [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md) class instance displayed in the [BitmapViewer](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_BitmapViewer.htm.md) has [ColorProfile](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Bitmap_ColorProfile.htm.md) initialized with correct color profile (e.g. it is embedded color profile loaded from file, or this property was initialized after the image has been loaded).

Color management engine is used to perform color matching while displaying the image. Suppose the property is set to [LittleCms](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_ColorManagementEngine.htm.md) or [AdobeCmm](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_ColorManagementEngine.htm.md) and the [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md) has [ColorProfile](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Bitmap_ColorProfile.htm.md) property initialized with a profile. Before image is displayed on the control, it is converted to RGB format with monitor profile as destination one. If you need to disable color management during displaying, set this property to [None](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_ColorManagementEngine.htm.md).
