As a seafood lover and amateur chef, I often find myself wondering – what color are raw shrimp? That beautiful coral hue we associate with cooked shrimp is nowhere to be seen when shrimp are in their natural raw state Through research and experimentation in the kitchen, I’ve gotten to the bottom of what makes shrimp change colors during cooking
In this article we’ll dive into
- The typical colors of raw shrimp species
- What makes raw shrimp look gray, black, blue, or green
- The science behind color changes during cooking
- How color indicates shrimp freshness and quality
- Pro tips for picking out raw shrimp
So read on to uncover the mysteries of shrimp coloration, from ocean to plate!
Typical Raw Shrimp Colors: Gray, Black, Blue, and Green
The majority of raw shrimp are grayish-black in their natural state The muscular tails of species like white shrimp and brown shrimp appear translucent gray with a dark digestive vein running down the back Tropical species like black tiger shrimp also tend to be gray-black when raw,
However, there are some vibrant exceptions! Decorative species like blue shrimp and green tiger shrimp contain unique pigments that lend them their namesake hues. And when it comes to tiny salad shrimp, they range from pale pink to clear in their raw form.
So while many of us imagine shrimp to be naturally pinkish-orange, they really do span the whole color spectrum before hitting the frying pan.
Why Are Raw Shrimp Colored This Way?
Shrimp get their base color from naturally occurring pigments like astaxanthin and canthaxanthin. Their shells also contain some yellow/red carotenoid pigments.
During cooking, the heat changes the structure of these pigments, resulting in that appetizing coral pink. But in their raw state, these compounds provide camouflage for shrimp in their ocean environments.
Interestingly, some shrimp even have the ability to change color by contracting and expanding their chromatophore cells. This helps them avoid predators by blending into surroundings.
The specific hue of a raw shrimp depends on its habitat and species. Those found in sandy areas tend to be more transparent, while shrimp living among seagrass and algae take on greens and blues as camouflage.
The Science Behind the Color Change
We all know cooked shrimp look different from raw, but what’s really going on from a scientific perspective?
It comes down to protein denaturation. The high heat of cooking causes the proteins that make up shrimp muscle to unwind and change shape. Astaxanthin binds to these proteins, so when they change, the color also shifts to the familiar pink tone.
Lower levels of heat, like grilling or sautéing, result in more subtle orange and coral shades. But high temperatures from boiling or broiling totally transform shrimp from gray to vivid pink.
Interestingly, this color change can also occur after death through the same protein breakdown process. Known as “pink death,” enzymes start digesting the proteins and change the pigments after a few days.
How Color Relates to Freshness and Quality
When selecting raw shrimp at the market, color can provide clues about freshness and overall quality:
-
Translucent appearance indicates higher water content and fresher shrimp.
-
Bright color with a sheen shows optimal freshness.
-
Yellow/brownish tint or murky color means lower quality.
-
Black spots are normal and don’t affect quality.
-
Unnaturally vivid hues may signal color additives.
Ideally, raw shrimp should glisten and feel firm to the touch. Be wary of any foul odor, which indicates spoilage. High-quality shrimp have a mild, briny scent.
Handling Raw Shrimp Safely
Since raw shrimp may contain bacteria, it’s important to handle them properly in the kitchen:
-
Store raw shrimp on ice at under 40°F.
-
Thaw frozen shrimp in the refrigerator, not at room temperature.
-
Wash hands and prep surfaces before and after contact.
-
Avoid cross-contamination by keeping shrimp separate.
-
Cook to an internal temperature of 145°F to kill potential pathogens.
Taking these precautions will keep you safe when preparing recipes using raw shrimp.
Picking Out the Best Raw Shrimp
Follow this expert advice when buying raw shrimp:
-
Look for firm, shiny flesh without many blemishes.
-
Make sure the head and legs are intact, not removed.
-
Smell for a mild, ocean scent – strong odors mean lower quality.
-
Check the color – pink death results in unnaturally bright hues.
-
For sustainability, choose U.S.-farmed or wild-caught options.
-
Ask trusted fishmongers for recommendations if unsure.
High-end grocers and seafood markets are your best sources for premium shrimp. With these tips in your back pocket, you’ll be able to select vibrant shrimp to star in your favorite marinara pasta, stir fry, or cocktail.
Raw Shrimp Color Takeaways
Who knew such a little seafood creature could be so complex when it comes to color? To recap:
-
Most raw shrimp appear gray or black, but some have blue, green, or pink hues.
-
Natural pigments help shrimp camouflage and adapt to their environments.
-
Heat alters shrimp proteins and associated pigments, causing the color to change.
-
Fresh, high-quality raw shrimp look translucent and shimmery.
-
Take care when handling raw shrimp to prevent foodborne illness.
-
Check for firmness, scent, and natural sheen when buying raw shrimp.
So next time you pick up a bag of raw shrimp, take a moment to appreciate their chameleon-like ability to transform. Getting that science straight is key to selecting fresh shrimp and using their full color-changing potential in your cooking!

White, Brown, Pink, Red: Learn the Colors of Gulf Shrimp
Common sense tells us that locally harvested seafood will taste fresher (and better) than a cheaper, imported product.
But when it comes to Gulf shrimp, that’s only the beginning of the story.
Gulf shrimp come in different species, and they are easily identified by color. This is different from Gulf crab and oysters, which are harvested and processed as a single species.
“Shrimp are thought of almost as a commodity,” said Chris Hastings, owner and executive chef at Birmingham’s OvenBird and Hot and Hot Fish Club. “But they each have their own characteristics and flavor profiles. I would challenge people to think of shrimp differently, not just as ‘all shrimp are created equal.’ Because they’re not.”
What does it matter what color you get? It’s the same with all Gulf seafood: its all about taste.
Because they eat a lot of iodine, brown shrimp have a strong flavor that goes well with hearty foods like gumbo and jambalaya.
White shrimp are found in less salty places, like brackish estuaries and bayous, so their flavor is milder and has hints of natural sweetness. If you boil or sauté them, they’ll soak in the nuances of the sauces and seasonings quite nicely.
Pink shrimp are also sweet, but their flavors are even milder. This makes them a good choice for dishes with light sauces, like shrimp and grits, and they grill up really well, especially with the heads on. They’re also the biggest of the Gulf shrimp species.
Then there are Royal Red shrimp, which are the best shrimp on the Gulf Coast. You’ll understand why after you try them. Since these shrimp have a rich, buttery taste that many people compare to lobster, you don’t need to serve them with a strong sauce.
You can’t really tell one Gulf shrimp from another once they’re cooked (except for the Royal Reds, of course). The trick is to find and cook them when they’re in season.
White shrimp are in season early spring and late fall when it’s cooler. In between those periods, brown shrimp are most plentiful during the summer months. Pink shrimp are your cold weather species, peaking from late fall until early spring. Royal Reds are off and on throughout the year.
There won’t be a big difference in price either, except for the Royal Reds.
“White and brown shrimp are close in price,” said Sea Pearl Seafood owner Greg Ladnier. “Pink shrimp go for slightly higher prices, and Royal Reds have a different market altogether.”
When shopping for Royal Reds, watch out for fakes. A lot of stores sell red shrimp from Argentina that are nothing like the real thing.
If you’re planning on seeking out Alabama Gulf shrimp soon for a family meal or a large get together, you’re in luck. According to Chris Blankenship, deputy commissioner of the Alabama Department of Conservation and Natural Resources and program administrator for the Alabama Seafood Marketing Commission (ASMC), Alabama shrimp are doing well right now.
“Shrimp is the most versatile Alabama seafood species,” said Blankenship. “As Bubba said in ‘Forrest Gump’, you can cook shrimp hundreds of ways. Whether it’s white, brown, pink, or Royal Red, Alabama shrimp is everyone’s favorite seafood. ”.
When you want Alabama Gulf shrimp again, plan what kind of dish you’ll make and check to see what season it is.
And, of course, make sure to ask your server or vendor to make sure it’s Alabama Gulf shrimp. Your taste buds will thank you.
“Gulf shrimp are all very distinctly different and interesting,” said Hastings. “And they’re certainly better than anything you could ever get from the imported standpoint. It’s not even remotely close. ”.
