Again using opaque beads as our baseline, some beads tend to attract more attention due in part to their surface finishes. Metal lined transparent beads, beads with a lustre or AB (rainbow) finish, and metallic beads, tend to come forward, reflect more light, or appear more intense than opaques.
Once you understand how a bead surface tends to behave in your composition, you can manipulate those surface finishes to create emphasis in a design, create a varied surface effect, and use other tricks to get parts of your composition to stand out more than others.
