I dont do traditional often anymore but when I did I always went with mixed media. I use polychromomos and they are the best colored pencils that I have used. Some may prefer to use polychromos and prismacolor together but I have never tried that personally.

For markers, I use copic. I’m not exactly up to date on the “best” art supplies but when I was more into traditional those were the most popular. Definitely not the most affordable and I’m sure you can find a dupe for them that are way cheaper but they blend nicely. Good for covering large areas.

For watercolor I use the Winsor and Newton Cotman watercolor miniature palette. I’m not exactly a watercolor expert so I can’t say anything other than they do the job… and they’re also the only watercolor palette I’ve used.

And as previous anons have said, for the white highlights I usually prefer sakura jelly roll pens (not sure on the lightfastness of these) or a polychromos/derwent chinese white pencil.

And for the paper I’m not an expert either but I use bristol for mixed media pieces.
