While the standard Chao eggs are white with light blue spots (as the standard Chao is light blue), other Chao eggs are the same color as the Chao inside them. Sonic Adventure: The Chao are virtual creatures that can be raised in Chao Gardens and used to compete in races to win emblems.(This was before the games introduced the breeding mechanic, as well as the idea that legendary Pokémon are unable to breed, with a few exceptions.) Pokémon Snap: The three legendary birds' eggs appear and can be hatched by the player - a crystalline silver egg for Articuno, a yellow egg with lightning designs for Zapdos, and a white egg with a flame design for Moltres.Magby's egg has flames on the bottom, Elekid's egg is yellow with stripes, Igglybuff's egg is pink with swirls, and Cleffa's egg is pink with stars. Pokémon Puzzle Challenge: Four eggs are available as unlockables.
Some of the eggs are just plain white, though. Based on their designs, the player can guess what Pokémon is in them and win money if they're right when the egg hatches.
Common, two-element eggs usually have the color of one of the involved elements and a pattern based on the other, with the pattern part colored gold if it's a rarer variant while rarer breeds have their own custom egg designs. Dragon Vale has dragon eggs that are designed after their dragons.For example, the origami dragon hatches from an egg made of folded paper. Dragon City: Eggs have the same theme as the dragons that hatch from them.Much of the game revolves around raising them from eggs to adulthood, so it's important that they have distinct appearances for easy recognition. Deep Seas are dark blue with raised patches of scales, as are their eggs Rift Wyrms are purple yellow and have purple and yellow eggs to match etc. Dragon Cave: Dragon and drake eggs are almost always the same colors as their eggs, e.g.Billy Hatcher and the Giant Egg: The player can obtain eggs colored like the various animals they hatch into.
