COLORREF CBCGPSmartDockingParams::m_clrToneDest

Specifies a color which should replace m_clrTomeSrc in marker bitmaps.

Fill this member when you wish to change a color of marker bitmaps programmatically. For example, if you need to display the standard library defined markers with another color, you have to fill this value with a custom color. The library assumes, that m_clrToneSrc is RGB (61, 123, 241) (the blue markers you see by default).

If you need to change the colors of custom markers, you need to specify m_clrToneDest in conjunction with m_clrToneSrc.
