Tried to use my favorite pattern (Link Pattern) that I've used for years and the pallet didn't work for New Horizons. Do the pallets not match up anymore?

the default pallet sets don't line up with the old ones, but if you buy the pro design editor with nook miles, you can change the individual colours to whatever you want

Awesome, thanks for the info. Any chance you'd know how to do that? Because I think I've got the pro designer but I'm a little slow at getting used to making designs right now

go to the tools section, and click the button that looks like a paint tube at the top (next to the paint pallet). you'll then be able to click between the colours with L and R

the colour selection works with hue, vividness, and brightness sliders, which can be a bit tricky to get the hang of if you're not used to that type of colour selection tool, but just mess around with it enough and you'll get it
