we dont use pantone colors but instead use Union Maxopaque lemon yellow, Union Maxopaque bright red, Union Maxopaque orange.
ever since our artist saw how the inks looked on and off the white base (on dark colors) - they always go for these colors. most times its just the lemon and bright red, but ive seen them use the orange a few times.
i tried using wilflex amazing base and pantones, but they still went back to the union Maxopaques
