The current parameters for the panel macro include:

title: Title of the panel
borderStyle: The style of the border this panel uses (solid, dashed and other valid CSS border styles)
borderColor: The color of the border this panel uses
borderWidth: The width of the border this panel uses
bgColor: The background color of this panel
titleBGColor: The background color of the title section of this panel

Can you add a titleColor? This will allow us to use dark backgrounds and set the text to white.

Thanks
