There is a _manila file you will have to manually edit. I will locate it here in a moment for you. In the meanwhile, you will need (2) things:

Manila Editor (Located here, XDA and Google)
Paint.net (located by Google search and free)

Locate the 1bbfdc9b_manila file or extract one from your device; save it to your PC. With Manila Editor open this manila and save the image to your computer. Then open Paint.net, open the image and change the calendar/call, etc icons to red or anything else for that matter. Save the image in .png format. Open manila Editor again to the same manila and click on "Replace". Select the image you edited and now you will have red highlights.

You can now edit other manilas the same way...
