Chromatic dragons

Chromatic dragons are types of dragons that appear in colours. There are four kinds of chromatic dragons, with several different dragons in each kind. From weakest to strongest, based on the standard adult form, the colours are green, blue, red, and black.

For more information on all types of dragons, see Dragon (race).

Green dragons
Unlike the other chromatic dragons, no baby green dragons have yet been seen on Gielinor, except for the green variant of the baby dragon Summoning pet and in the dwarven Power Station during the Perils of Ice Mountain quest.

Blue dragons
During the Perils of Ice Mountain quest, a blue dragon hatchling can be seen in the power station, but players cannot interact with it.

Red dragons
During the Perils of Ice Mountain quest, a red dragon hatchling can be seen in the power station, but players cannot interact with it.
