Transfer foil is probably available in all possible colors. We will get more subdued and crazy proposals. In a light mat and flash. The most popular are those in the holographic version, which change different colors depending on the angle of incidence of light.
Another type of foil is foil with patterns. These are less common because they are used less frequently. You can find proposals with animal motifs and those more popular in winter with snowflakes. Of the patterned foils, the most popular are the geometric ones, where the holo breaks beautifully. In short, the color rainbow madness wins. Other suggestions that I saw on the pages and caught my attention are gasoline-spilled mazys, very delicate foils with a pearly glow, and individual patterns that look like stickers on the nails.
