I'm trying to replicate the effect of this LED panel I found at Home Depot with a different set of LEDs and use a differently sized panel. It's basically just a diffused light that mimics a window or skylight.
Upon inspection, I realize that it uses some type of edge lit material, but I'm not sure what. My goal is to diffuse light through the panel uniformly using an RGBW strip, maybe something like Philips Hue. I'm not sure if the panel should be clear with a backing or frosted.
What are the best materials to use for this?

"Edge-lit" seems like a strange design choice for something intended to provide that many lumens over a 2x2' area when an array of LEDs behind a decent diffuser typically works well...

Strange or not, they work really well. Installed two 2x4ft panels in the basement, more than doubled the available light output, and the light is very even across the entire surface. Halph, I'd suggest researching how LCD backlights work; those spread the light evenly across the whole surface but there's more than a little magic to it.

These panels are built in the same way as LCD monitors with LED backlight. Well, monitors have a LCD in front of the backlight panel, but you get the idea. Here's a monitor teardown.
The important part is a thick transparent acrylic plate which acts as a light guide via total internal reflection. It is lit through its edges. And... there is a pattern etched on it which breaks the total internal reflection in order to allow the light to get out through the front side. Without this, the light would only get out of the plate through the edges, and that would be useless.
The acrylic plate is the center of a sandwich, with a white reflector on the back, and one or more sheets of diffuser material in front. A LCD monitor will also have polarizers and, of course, a LCD.
All this is not DIY friendly, but you can get the whole kit for free if you find a busted LCD TV or LCD monitor. Thus... try dumpster diving. Get rid of the LCD and polarizer, and keep only the backlight plate and reflector/diffuser films.
