basically what the title says.
for actually getting the Color to find:
or using a button where you press down, and release over the selected color, use this as an example
in this case, a picturebox called PictureBoxColor has its background color changed to the hovered over color.
Private Function findColor(ByVal Color As Color, ByVal Area As Rectangle) As Point
Dim AreaSize As Size = Area.Size
Dim TempBitmap As New Bitmap(AreaSize.Width, AreaSize.Height)
Graphics.FromImage(TempBitmap).CopyFromScreen(Area.Location, New Point(), AreaSize)
For x As Integer = 0 To Area.Height - 1
For y As Integer = 0 To Area.Width - 1
If TempBitmap.GetPixel(x, y) = Color Then Return New Point(Area.X + x, Area.Y + y)
Next
Next
Return New Point(-1, -1)
