Overview
The Pastel is one of the most popular and foundational colour morphs in the ball python hobby, prized for its brightened yellows, lighter background and cleaner pattern. It is easy to produce, inexpensive and forms the building block of countless combo morphs. Pastel is a colour and pattern morph of the ball python (Python regius).
What it is
Pastel is a single-gene morph that lifts and brightens the animal's colouration compared to a normal (wild-type) ball python. Where a normal ball python shows muted browns and tans, a Pastel shows more vivid yellows, a lighter and often cleaner-looking pattern, and frequently paler "blushing" along the sides and top of the body. It changes only the animal's appearance, not its size, behaviour or biology.
The genetics
Pastel is an incomplete-dominant trait. In the hobby it is usually called "co-dominant," but technically it is incomplete-dominant: one copy of the gene produces the visible Pastel look, and two copies produce a distinct, more extreme "super" form rather than simply masking the other allele. The double-copy animal is the Super Pastel, which is brighter and more washed-out than a single-gene Pastel and often shows reduced or faded pattern and lighter eyes. Because a single copy is visible, Pastel is also one of the most commonly stacked genes in designer combos.
Appearance
A single-gene Pastel typically has a yellow-forward base, lighter and higher-contrast blotches, and paler flanks than a normal. Head colouration is often greener or brighter, and the eyes can be a lighter shade than a normal's. Many Pastels "brown out" somewhat with age, losing a little of the vivid yellow they show as hatchlings, though they usually remain noticeably brighter than a wild-type. The Super Pastel goes further: a much lighter, faded background, reduced pattern and often pale, silvery eyes.
How it is bred
Because Pastel is incomplete-dominant, only one copy of the gene is needed for the look, so any visible Pastel bred to a normal will pass it to roughly half the clutch on average. Pairing two Pastels together can produce the double-gene Super Pastel alongside single-gene Pastels and normals. To make combo morphs, breeders pair Pastel with other single-gene or recessive morphs so the offspring inherit and stack multiple traits at once. No hets or hidden carriers are involved, since the gene is always visible when present.
Cost and availability
Pastel is extremely common and one of the most affordable morphs available. Single-gene Pastels are widely produced and sit at the budget end of the market, while Super Pastels and Pastel-based combos cost somewhat more depending on what other genes are stacked in. Availability is high year-round from hobbyist and commercial breeders alike.
Health and ethics
Pastel carries no known genetic welfare problem. It is not linked to the neurological "wobble" seen in some morphs, and the Super Pastel (the double-gene form) is fully viable and healthy, not lethal. The morph itself needs no special health considerations beyond normal ball python care. As with any animal, choose reputable breeders who prioritise health and temperament, and consult a reptile (herp) veterinarian for any health concerns. Caution is only warranted when Pastel is combined with other genes that do carry welfare issues, in which case those specific genes are the concern, not Pastel.
Care
Care is identical to a standard ball python. The Pastel gene changes only appearance, not the animal's needs, so the same enclosure size, heating and thermal gradient, humidity, hides, fresh water and appropriately sized prey all apply. Follow reputable, up-to-date ball python husbandry resources for full setup details, and see a herp veterinarian for any health questions.

Pastel Ball Python - frequently asked questions
Is a Pastel ball python co-dominant or incomplete-dominant?
In the hobby it is called co-dominant, but technically it is incomplete-dominant: one copy shows the Pastel look and two copies make a distinct Super Pastel, rather than one allele fully masking the other.
Does the Pastel gene cause any health problems?
No. Pastel has no known genetic welfare issue, and the Super Pastel double-gene form is healthy and viable, not lethal. Care is the same as any ball python.
