Blue-breasted bee-eater characteristics. It has a blue stripe over the black eye stripe, an orange-red iris, a white cheek and a bright yellow throat. Furthermore, like many members of the Meropidae family, they have a wide chest band. Its chest band is made up of two colours, a deep purple-blue gorget above a chestnut coloured breastband . Juveniles of the blue-breasted bee-eater have buff flanks and belly. They have a yellow-buff chin that leads to a light green mottled breast. Juveniles also completely lack a chest band. The little bee-eaters and the cinnamon-chested bee-eater are both very similar to the blue-breasted bee-eater.
Budgerigar colour genetics from oranges, peaches, pinks to reds. When these feathers are exposed to a white light source, such as sunlight, only the blue part of the spectrum is reflected by the eumelanin granules. This reflected blue light passes through the yellow pigment layer, resulting in the green colouration known as "lightgreen" in only the budgerigar and/or "green" in any other naturally green coloured parrot species. The many colour variations of budgerigars, such as albino, blue, cinnamon, Clearwinged, the various Fallows, Grey, Greygreen, Greywing, Lutino, Mauve, Olive, Opaline, Spangled, Suffused and Violet are the result of mutations that have occurred within specific
