Change Form color constantly
To start with, your current code doesn't work, but not because of any threading issue (although that does need to be solved). The issue is that these lines never get hit: custom = Color.FromArgb(contr, contg, contb); this.BackColor = custom; The logic in your while loops just don't work. The values...

android,colors,datepicker,calendar,selector
Okay I think I got it. I tried desperately to find an attribute in MyDatePickerStyle. The solution came to my mind when I rethought the whole inheritance hierarchy.

Problems with changing colors in chart winform
c#,winforms,charts,colors,series

To avoid this, you need to explicitly set the colors of all series. See http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.series.palette(v=vs.110).aspx...
