Yes. You can layer substrate in any tank. However, if your plants can grow fine in gravel, they can grow fine in colored gravel, just make sure the colored gravel is safe for aquariums.
The gravel is put into shakers with different size screens, with the screens with the larger holes on top. The gravel is then shaken, forcing the different sized rocks through the holes, which separates them according to size.
Most aquatic plants require gravel, as they have roots, and will need to grow their roots and attach themselves. There are however lots of floating plant species that do not require gravel, such as duck weed.
