Select Color Source Select "Use System Colors" to use the Windows scheme (available in Display Properties, Appearance)
When System Colors are used in conjunction with 3D keys, only pure RGB colors are allowed. (RGB - Red, Green, Blue - 3 values between 0 and 255 indicating the amount of Red, Green, or Blue used to "build" a color - this is sometimes referred to as 24-bit color (3 x 1 byte <=> 3 x 8 bits = 24 bits) - pure RGB means a value of either 0 or 255 (no bits set, or all bits set)) Due to the shading & desire for a clean appearance, preservation of the system color is not possible (disable 3D keys to see actual system color). The following algorithm is used to create a "pure" RGB color: The system color is split into the 3 RGB components, and then the smallest value is subtracted away from all elements, leaving 0, 1, or 2 positive values - these then are used to determine use of a solid color (i.e. value of 255) or no color (i.e. a value of 0). This is used as the "background" of the shaded keys. In most cases, this is in the same color scheme as the System Colors. You may adjust the Windows Appearance, "Display 3D keys", or revert back to "Use Panel Colors" to review the various display options.
