Oil Spot Crested Geckos
The Oil Spot morph produces faint, greenish Dalmatian spots on a crested gecko that appear washed out instead of solid black. Because these spots can disappear when the gecko fires down, judge them based on a fired-up photo instead of counting them on an unfired one.
About the Oil Spot gene
The Oil Spot is a type of Dalmatian spot found in crested geckos. While a standard Dalmatian spot is a solid dot, an oil spot appears faded. It looks as though the colour never fully formed and it normally has a green or grey tint. When a listing names Oil Spot, it refers to that softer, greenish mark.
Appearance
The size of a spot affects how its shading looks. For smaller oil spots, the centre is usually the darkest part and the colour fades toward the edge. Larger spots have a faded centre and a darker rim where the base colour of the gecko shows through the faded part. These spots can appear or disappear depending on the colour state of the gecko. They show when it is fired up and drop out of sight when it fires down, so counting them from one unfired photo can come up short.
Genetics
Oil Spot is a polygenic trait that is grouped with Dalmatian in the spotting category. This trait is listed as Oil Spot and Pos Oil Spot, though some keepers call it Green Spots. Within Dalmatian spotting as a whole, green is the least common and black spots are the most common. No originator or first year is recorded.
