I want to create a simple timer, but I want the display to appear like a digital clock, such that you can see the grey template of 88:88:88 and the actual display numbers being a much darker overlay.  I thought of having two TEdit boxes, the first with a grey font of 88:88:88 and the second with black font and a clear background, but I don't seem to be able to give the TEdit control a see-through background.  Annoted/Explained Code preferable

i'd go to another way....
A Timagelist with 11 images (for 0 to 9 in led style and the : sign) then a panel with 8 Timage.
On timer read the Time String value (for example 13:00:12) and assign to the same pos image  the correspondent image from imagelist....It's just an idea, but so you can customize your images, and so your digital numbers, as you prefere.....

btw to use your idea should be bettere to use a led styled label....there're lots of led label components on the web and expecially on torry.net

in this package there's TPieLedLabel with source that's a good solution for your job

It seems wasteful of resources though, I would have thought that maybe subclassing the Tedit and fiddling with its background properties to allow it to be transparent would be better, but I have no idea how to!

so go to a more simple way....use 2 tlabel, the first with font color clInactiveCaption.
The second exactly over the first with font color clblack and transparent property to true....the easiest way...
