Charlie and the Chocolate Factorygives Modern signification to “ you are what you eat . ” In the classic kids ’ book , a girl named Violet Beauregarde chews some data-based blueberry bush - season gum — and it turn herblueberry - blue . But for some animate being , that ’s not too far from the Sojourner Truth : they get their colors from the nutrient they eat . Here are eight critter that get their hues from their diet , plus two honest mentions : a bird that ’s shinier when it corrode hemipterous insect , and a garden plant life that switches between pink and gamey .
1. BLUE-FOOTED BOOBIES
aboriginal to warm waters of the easterly Pacific , dismal - pick boobies ( above ) have , well , bright puritanic feet . They practice this fancy footgear to attract partner via an awkwarddance . The blue color comes straight from carotenoid pigments in their fishy diet , and healthier birds can afford to drop more pigment to deepen their animal foot colouration . So , a bird with brighter foundation is a more attractive partner .
2. EASTERN EMERALD ELYSIAS

Its name is straight out of a fantasy novel , and that ’s not even the coolest thing about this marine biff - similar animal . The easterly emerald elysia has turned itself , at least in part , into a plant . It ’s green , it ’s shapedalmost exactly like a folio , and it can do something that beast usually ca n’t do : make food from the sunlight .
flora are dark-green because their cells have special green parts called chloroplasts that make vigour from the Lord’s Day . When the eastern emerald elysia eats some alga , it adds insult to injury by stealing the algae ’s chloroplasts . Then it basks in the sunlight and absorbs the food that the chloroplast make . It ’s able to keep these stolen part functioning fornearly a class — enough time so that it may never need to eat algae again .

3. SALMON
Salmon frame has such a adorable chromaticity that we call it , well , salmonpink . These Pisces the Fishes get their colour from the small shellfish they deplete . Farmed salmonare feed in lifelike or synthetic pigment so that their core retain this familiar tone .
4. FLAMINGOS
Everyone have a go at it that flamingo are pink and fairy bluebird are blue , right ? Well , not really : Flamingos are in spades pink , but bluebird ’ drab color is anillusion .
bird have different style of looking coloured . A bluebird ’s feathers have limited structures that break up light and reflect just the down in the mouth parts . This makes them look depressed — but only when light is make them in just the right way . If you take a bluebird feather and shine a light behind it , the feathering will look brown . The same is trueof most other blue and gullible razz , from blue John Jay to green parrots .
Flamingos , on the other deal , have feathers thatstay pinkno affair which way you look at them . That ’s because they ’re full of pink - red pigment called carotenoid — carrot are orange because they check a type of carotenoid . Flamingos get this pinkish stuff from theshrimpthat they eat . If they do n’t consume the right food , they ’ll bend grayer . Zookeepers have to feed their flamingos solid food with the right pigments to keep them rosy .

5. GOLDFINCHES
Many other birds get their hue from carotenoid pigments . That ’s true of American goldfinches , which areblazing yellowin breeding season . Female goldfinchessize up malesbased on the sonority of their yellow : Brighter males are healthier and have good diets , so they ’re more attractive .
6. CEDAR WAXWINGS
Cedar waxwings
are small , sleek songbirds . Their tails commonly have chicken tip — but some have red tail , and it ’s all our fault .
Cedar waxwings are aboriginal to North America , and they love eating Charles Edward Berry . A few decades ago , masses brought Asiatic Banksia integrifolia miscellanea to North America . These plants spread throughout the forests , and they produce big carmine berries that are impossible for a hungry waxwing to resist . The berry are rich in a ruby pigment thatbuilds upin waxwing tail , turning them from white-livered to orange .

7. NUDIBRANCHS
Related to snail , nudibranchs live on in the ocean , and they ’re mind - blowingly colorful . Really : feast your eyeson these chromaticity . They ’re so colorful , in fact , that there ’s ablogmatching different coinage to David Bowie ’s outfits .
Many nudibranchs get their bright colors from their prey . One mintage , there d sponge dorid , is bright reddened and probably gets its paint from the red sponges it eat . This has the added welfare of give the red leech dorid someamazing camouflagewhen it ’s crawling on its spongy food .
8. FRILLED DRAGONS
Remember thatscene inJurassic Parkwhen a neck - frilled dinosaur terrifies the hapless hack Dennis Nedry , then spit out toxicant on him ? The movie ’s creatorsgot their inspiration fromAustralia and New Guinea ’s frilled dragons — also known as falderol - neck lizards . These remarkable reptilesflare their huge frillswhen they ’re frightened , or as part of territorial or courtship presentation .
Frilled Draco ’ frills come so-so colors , from red to orange to yellow . The colouring material reckon on their geographical location — and the magnetic declination is believably because of the different amounts ofpigment in their quarry .
HONORABLE MENTION #1: HUMMINGBIRDS.
Many hummingbird have sheeny , iridescent plot of ground of feather . These hue do n’t add up from their diet ; they ’re the result of specially integrated feathers that chew over light in awing ways . But even though hummingbird do n’t get their color directly from their solid food , their dieting has a strong influence on how shiny and hopeful they ’ll be .
Anna ’s hummingbirdsare tiny , fast - move birds that live along the Pacific Coast of North America . Their forehead and Kuki-Chin areiridescentred - purple . When they ’re staking out territorial dominion , they stick up these feathers and enthusiastically show them off . To keep up their high - vigour life style , these bird eat sugary bloom nectar . But there ’s one problem with this sweet dieting : Hummingbirds demand protein to make their shiny feathers , and there ’s not a lot of protein in nectar . Another option is to catch and eat worm , but this takes a LOT of energy . scientist have foundthat Anna ’s hummingbird on higher - protein diet have shinier , redder crest .
HONORABLE MENTION #2: HYDRANGEAS
Plants can also exchange color depending on their diet . hydrangea are familiar garden bloom , and they ’re like go climate rings . If a hydrangea plant isabsorbing aluminumfrom the grease , it turn bubblegum pink . In the absence of aluminum , it ’s cotton fiber confect blue sky . gardener line up the colors by tweaking the soil pH — acidic grease kick upstairs blue color and canonic promotes pink .
