I made a list of parts to replace to decolor the 10327 Dune Ornithopter (explanation and text version in description)
I made this list based on the instructions PDF that's available from LEGO's website. For most of these, it doesn't really matter if they are black, dark bluish gray or light bluish gray so I picked them based on what will most likely look good with the surrounding colors and what is cheapest on Bricklink.
In general, if you want to save a few bucks, you can probably leave all tan and white pieces as they are. For me, the complete replacement (250 pieces) cost about 35€ plus shipping.

Because the general consensus among pretty much all reviewers was that it’s a great set but the colored pieces (especially the blue and red technic pins) look very ugly in an otherwise monochrome set.
Some of the pieces on the inside may not need to be replaced but because I don’t have the set here yet I can’t tell which ones are visible from the outside and which ones aren’t so I included all of them.
For now, only reviewers got theirs. Regular customers like me will have to wait until late February or early March.
I made this list based on the instructions PDF so I can already order the replacement parts from Bricklink and start building as soon as the set is here.
There is no magic or special knowledge involved. I just went through the instructions step by step and for each unnecessarily colorful piece, I picked a replacement color that should look good, based on the surrounding pieces.
Oh cool! Where did you order it? Lego's website says late February and JB Spielwaren where I ordered (because they include a cool display stand for the minifigs) currently estimates the shipping date as early March.
I had mine pre-ordered through Amazon! I’m actually kinda a newb to legos so this is only my 2nd set. Finished the R2D2 earlier this year. Now I want the display stand though cause I’ve been trying to figure out what to do with the minifigs so I don’t loose them🤣
