I had a similar issue with my Revell Porsche slantnose. It was red plastic, and I was originally going to paint it pearl white, but the plastic bled through. Came out a pretty pearl pink when I was done.
Used it on a couple of kits so far. Used the matte blue for my Tyrrell P34 (yeah I know, it's metallic) and I'm using the neon green for a 2008 Dodge Charger Super Bee. Makes a decent replacement for Sublime Green. Dries really quick, and no real awful smell more than any other paint.
Mischief Managed! Found out that the USB port under the dash will pick up a thumb drive and the stereo will read MP3, so I loaded a 15GB one with a bunch of ripped music Now I've got Dream Theater, Fates Warning, Grim Reaper, Avantasia, Kamelot....
Had a 2011 GMC Acadia that died about 3 weeks ago (last few weeks have been an "adventure"). Alternator went out and after it was replaced it just never started again. Was able to get a 2020 Chevy Equinox with 132000 miles for $8400. It's in great shape and drives well. I miss the CD player, but I'll manage.
Right now I don't even have a 1:1 running car. Acadia ate the alternator, now it wont start after replacing. The loaner ran for about a week, and it wont start now either.
I remember a White Dwarf magazine where they were doing patterns like this on a Falcon Grav Tank. If I remember correctly they shot it with a base coat, used a mesh (from a bag of oranges in this case) and stuck it to the surface using 3M spray adhesive. Once the mesh was in place, they sprayed the second color and removed the mesh. Maybe use a finer mesh, and spray the lighter color first, then spray the darker color over it?
I've done this on my Star Trek ships. I typically apply the insignias and hull markings over matte paint or even Dullcote. I dip a brush in decal set and then white Elmer's glue and paint it directly on the surface while the decal soaks. Slide the decal onto the puddle of glue/set and move it into position, then work it down with a Q-Tip and blot dry. As it dries, the decal set will help pull it into the crevices and settle over curves and the glue will help keep it from silvering. If there's any excess on the surface of the decal, a little Novus 1 on a Q-Tip will remove it. I hope this helps.
