Now add some white, just wherever, doesn’t matter, there’s no science to it. Don’t cover all the yellow though. Let it dry.
If you have a palm sander use it to rough up some areas of the white, revealing some yellow beneath. Use a dry paintbrush to get all the sanding dust off.
Time to add the red. This time you do want to cover most of the color underneath.
Now you’re going to use some masking tape to pull off some of the still wet red paint. Not everywhere, just here and there. Let it dry.
Use that palm sander again to start distressing! Rough of the edges of course, and anywhere else you want to reveal color underneath. It’s totally up to you how much or how little you do.
Add some antiquing gel wherever you think it needs it.
Let it dry (again) then add some clear acrylic sealer.
