Their general background color is yellow and lavender, although a number of new color phases have arisen through captive breeding.
Some of the existing phases are animals with hi-yellow, white or lavender background color, striped, jungle and other pattern anomalies,
and leucistic (actually hypomelanistic) and albino genetic mutations.

Determining special colorations of Leopard Geckos:

1.  For a leopard gecko to be Jungle Phase, it MUST have an unringed tail.

2.  Tangerine, High Yellow, Hypomelanistic and Snow are products of selective breeding, and are therefore usually more expensive than others that are a
product of a simple recessive gene, such as pattern less.

3.  Some people are selling 'Tangerine' Leos based on what their parents look like. 

4.  Some breeders will advertise a Lavender gecko that is simply in the midst of its colour change where the dark bands break up into spots. 
When this happens, there's a little bit of purple that comes out, but it is normal.

5.  The Albino Debate - It has been all but proven that the two strains of leopard gecko albinos that have surfaced in the last couple years are different.

Here's the general lowdown on breeding for different phases of leopard geckos.  Selective breeding produces all phases or colour morphs that are NOT genetic,
such as Tangerine, Snow, Hypoxanthic, Hyperxanthic, High Yellow and Lavender. That is, they were created by breeding parents who also had those traits, but the off spring may or may not exhibit these traits. Phases such as Patternless, Albino, Blizzard, and Jungle are recessive genetic traits and will be passed down from two parents
who are carrying AND exhibiting this trait (homozygous).  This is not the case when you breed one parent who has and exhibits the gene with one that carries
but doesn't exhibit (heterozygous), or a normal leopard gecko.
The following are statistical outcomes of breeding pairs of Albino leopard geckos:

Albino to Albino = All Albino offspring (provided they are same strain of albinism)
Albino to HET Albino = 50% Albino / 50% HET for Albino
Albino to Normal = All HETs
HET to HET = 25% Albino / 50% HET / 25% Normal
