Here's what the TRD shift knob looks like color-matched to the platinum color of the early years dash (2010 in this case).
Also painted over the red stitching with black steering wheel paint. Added some plumber's tape to the threads so it would tighten up before bottoming out. If it bottoms out, it will hit the side of the shift bezel when shifting in/out of park.

By the way, there is limited ability to disassemble this thing, but the trim piece around the top can be removed fairly easily. There is a little clip in the front and a big glob of adhesive in the back.
Using a plastic spudger tool (not a metal screwdriver), pry up the thin front edge part closest to the dash. You'll hear a tiny clip pop loose. Then use a heat gun or hair dryer to gently warm the large section that sits below the TRD letters. Using your fingers to gently pull up on the thin front edge, use the spudger tool about halfway down one side to pry the back panel apart. Once you hear the adhesive letting go, switch to the opposite side and pry there. It should come off easily.
