Lightfastness | How long will it resist fading?

• Each pigment is rated on scale by the American Society for Testing & Materials (ASTM). Liquitex paints are all rated ASTM I (excellent) or II (very good) and considered permanent and lightfast for 50-100+ years in gallery conditions. Our metallic and fluorescent colors are naturally less lightfast.
  

Opacity/Transparency | We communicate opacity/transparency clearly on our packaging based on three categories:

• Opaque: these colors do not allow light to pass through the color layer and offer the best coverage or hiding power.
• Semi-opaque: these allow for some light to pass through the color layer and sit between opaque and transparent colors
• Transparent: these colors offer the least coverage and allow light to pass through the color layer to the surface below.
• Series:
  Pigments come from a variety of sources and have different prices according to their rarity, processing and milling costs. We group our colors into a 'series' pricing structure according to how much each one takes to make. Series 1 colors contain the most inexpensive pigments, while Series 4 and 5 color contain the most expensive pigments.
