Pigment density determines how glitter reads against dark backgrounds. Art Institute's Ultrafine Opaque Glitter maintains full color intensity regardless of the surface beneath it, black cardstock shows the same rich red or deep purple as white paper does. This opacity comes from heavy pigment loading similar to acrylic paint formulation, delivering jewel tones that stay true rather than appearing translucent or washed out.

The ultrafine particle size creates smooth, even coverage without the chunky texture of standard craft glitter. Non-toxic polyester construction provides durability and color stability, while select metallic-enhanced colors (copper canyon, hot lava, ice, Inca gold, light gold, persimmon, sand, sea, yellow) add dimensional shimmer beyond flat opacity. Whether layering over painted surfaces, adhering to colored papers, or building up dimensional effects, the pigment concentration ensures your color choices remain accurate and vibrant.

Half-ounce jars provide substantial coverage, ultrafine particles go further than coarse glitter while maintaining professional results. Mixed media artists working on dark substrates and cardmakers requiring consistent color across varied backgrounds find this opacity essential for designs where glitter color must read clearly without the base surface showing through.
