Pacapillars with a standard chameleon mutation can either change their colour or their pattern but not both. Pattern change allows pacapillars to change their markings, but keep the colours and all other traits the same (eg; switching between pink stripes and pink spots). Colour change allows a pacapillar to change it's colour but not it's markings or other traits (eg; from red stripes to blue stripes). "Standard" means that only one of the two is allowed, this mutation is not exclusive to standard pacapillars, and can apply to all the subspecies as well as split pacapillars. In masterlist images, the alternate colours/patterns of the pacapillar should be shown as well.
