Change color of title bar on agenda/month view of stock calendar widget?

[robo456]

I have a few calendar/agenda widgets that I've purchased from the Play Store, but I like the simplicity of LG's stock calendar month view (full page) and the agenda (showing the next 4-5 days). However, I can't seem to change the color of the title bar. I can change the title itself, and of course the colors of the events, but not the bar.

I have a blue/green motif going on, and I seem to be stuck with the bright red stock color of the calendar bar. Is there any way to change it?

Thanks for any info!
