By default, the RenderType property is 0, which indicates that the colors are being applied to EBN object. Imagine that an EBN is just a Color. As you would paint an object using a solid color, the same you can use using the EBN objects. Shortly, all properties or parameters that support EBN objects is indicated in the help file with the description "The last 7 bits in the high significant byte of the color indicates the identifier of the skin being used to paint the ...." A color expression is generally a combination of RRGGBB values, even it is stored in a DWORD value, which means 4 bytes, so actually the color uses only 3 bytes for RR, GG and BB value, ( red, green, blue ). This way we get one byte that can be used to specify the identifier of the EBN being used. For instance, 0x1000000, indicates the EBN with the identifier 1, since 0x000001, means actually the RGB(0,0,1) which is different. If you need to paint the EBN with a different color, you need to specify the RRGGBB values, as 0x1FF0000 means the EBN object being shown in red as the 0xFF0000 is RGB(255,0,0) which means red, and the 0x1 indicates the EBN with the identifier 1. All controls the support EBN objects provide a VisualAppearance collection. Use the Add method of the VisualAppearance collection to add new EBN objects to the component.

For instance the Color = 0x1000000 indicates that the EBN with the identifier 1, is being displayed on the object's client area. We can use the same EBN object with a different color, by changing the RGB values when setting the Color property such as: Color = 0x1FF0000 applies the EBN with the ID 1, using a Blue as a background color. 

The way EBN objects are shown on the objects can be changed using the RenderType property such as follow:

• if -3 (0xFFFFFFFD), no color is applied. In this case a Color = 0x1000000 or Color = 0x1FF0000 displays the same EBN object with no color being applied. In other words, the RGB value in the Color property is ignored or not applied
• if -2 (0xFFFFFFFD), an OR-color scheme is used to apply the color on an EBN object. In this case a Color = 0x1000000 or Color = 0x1FF0000 displays the same EBN object, no color applied for 0x1000000, and 0xFF0000 color being applied on the second. The look or the visual appearance of the second EBN uses the OR-color scheme to show the EBN object with a different color.
• if -1 (0xFFFFFFFE), an AND-color scheme is used to apply the color on an EBN object. In this case a Color = 0x1000000 or Color = 0x1FF0000 displays the same EBN object, no color applied for 0x1000000, and 0xFF0000 color being applied on the second. The look or the visual appearance of the second EBN uses the AND-color scheme to show the EBN object with a different color.
• (default), 0xTTRRGGBB, any other value indicates a pair ( transparency, color ) to be applied to ALL EBN objects. The first significant byte indicates the transparency ( a value from 0 to 100 ), while the other bytes indicates the RGB value. For instance, 0x32FF0000, indicates a transparency of 50% with a blue color, so a 50% blue is begin applied on the EBN to be displayed. This option can be used to apply a color to the entire component, or to show the component with more blue for instance. In other words, the format for RenderType property is AABBGGRR, where the AA could be a value between 0 and 0x64 ( 100 % ) and it indicates the transparency to be applied, and the BBGGRR indicates a RGB color. The RGB color is being applied ONLY if it is not 0x000000 or 0xFFFFFF, In this case the original Color property may indicates the new color to be applied on the EBN object.

The following screen shots shows an EBN object with different type of rendering ( RenderType property ):

• RenderType = -3,
• RenderType = -2,
• RenderType = -1,
• RenderType =  0x00000000,
• RenderType =  0x32000000, , 50% Transparent (0x32 = 50), Black ( 0x000000 is 0 or RGB(0,0,0) )
• RenderType =  0x64000000, , 100% Transparent (0x64 = 100), Black ( 0x000000 is 0 or RGB(0,0,0) )
• RenderType =  0x320000FF, , 50% Transparent (0x32 = 50), Red ( 0x0000FF is 0 or RGB(255,0,0) )
• RenderType =  0x640000FF, , 100% Transparent (0x64 = 100), Red ( 0x0000FF is 0 or RGB(255,0,0) )
