My color well has a little triangle on it? (NSColorWell->General)

If your color well has a little triangle in the corner after you set the color programatically, that probably means the NSColor you used was created in Device space (e.g. colorWithDeviceRed:green:blue:alpha:) If you use a Calibrated color (colorWithCalibratedRed:green:blue:alpha:), the triangle goes away.
