Designing: Lampworked




  • Lampworked creates abstract swirls across a ketucari that can optionally be filled with an accent color.
  • In your ketucari’s genotype, lampworked is represented by “nLwk” (heterozygous) or “LwkLwk” (homozygous)
  • In its heterozygous form, lampworked has a passrate of 30%. Homozygous lampworked has a passrate of 55%

Color and Shape


Lampworked creates colorful swirls across the coat of your ketucari, similar to the designs found in lampwork glass beads and similar designs. Swirls can optionally be filled with an accent color. Both the main and accent colors can be any color. Lampworked can be hard or have a slightly blended edge, but must not be so blended that it resembles haze.

Blobs of color ringed by an outside color is another legal presentation, and can occur with or without swirls. 

These are some samples of what the “main” part of lampworked can look like-- shapes can be stylized (appearing like hearts, flowers, or leaves, for instance), but should be abstract rather than detailed. The accent color should be surrounded by the main color, though some small gaps are allowed. While some top-to-bottom stripes are allowed, they should be a small accent and not appear as the only presentation so as not to closely resemble lionfish.

This is approximately the maximal stylization allowed for lampworked-- please note that while the shapes are stylized (taking flower and vine forms), the shapes used to make them are simple loops, whorls, and points. This also shows the inner color fading into the base coat, which is an option for open loops and similar shapes. (Please note that the lightest purple in the design is from Plumage, and is not part of the Lampworked.)



Lampworked may appear on any part of the body. It must not cover more than 50% of the body, but must cover enough that it is immediately recognizable.


Interaction with Other Markings

  • All markings may be layered under or over Lampworked.
  • Lampworked may be affected by Inferno or Vapor- in that case, it should only affect EITHER the main or accent color.
  • Lampworked may also be affected by Morpho and Jovian, and those modifiers can affect the entire marking.
  • When present with Eye Spots, Lampworked can use an additional color, for a total of 3.



When Lampworked and Stamped are present on the same geno, they can combine to create a marking resembling the patterns of millefiori glass-- small concentric shapes with Lampworked’s accent color present in some part of the shape. 

Millefiori doesn’t have to take a flower shape, but it needs to have radial symmetry and one or more concentric pieces.


  • Lampworked may have a subtle gradient and fade into the base coat.
