Is it an actual blue pigment...or a physics thing where they scatter the light and appear to be blue (structural colouration)?

They're known to eat a lot of fish & crustaceans, so it seems likely that the carotenoids are dietary.

There's not a lot of research on the pigmentation chemistry in these species, but plenty in the shared taxonomic family, Alcedinidae.
Kingfisher feathers – colouration by pigments, spongy nanostructures and thin films
SUMMARYThe colours of the common kingfisher, Alcedo atthis, reside in the barbs of the three main types of feather: the orange breast feathers, the cyan back feathers and the blue tail feathers. Scann...

for the colour one I tried to reference one ref for shape/shading and a different one for actual colouration and i don’t think i’m big brained enough for a move like that yet bc i was fucking struggling lol

Though that is a false promise. Unlike purification the flower does not actually rid someone of their manifestations, instead drawing them back into a person like an anima drain. Yes, this will get rid of the purple colouration associated with falling.

She’s back! A lovely #aurora display after sunset tonight with pink visible by eye and the camera revealing beams and much more intense colouration. Has died back again just now but should be a good show throughout the night. #northernLights #astrophotography #photography #stormHour #photoHour

One of my favourite locations, St Ouens Bay, Jersey. The storm had blown through and an evening autumn sun breaks cover to cast a warming glow. Sunlight catching long beach grass and a backdrop of La Rocco Tower and Corbiere.

Photo taken from grassy bank with long beach grass and blown vegetation. The evening sun catches the grass. Overlooking the grass verge is a rather stormy sea with a prominent sea tower and lighthouse in the distance. A hazy sunshine gives yellowish/grey colouration to the clouds as a storm front has blown through. An image of quite significant depth and interest.

This is something truly special. I love the colour of the sky and the clouds. - The framing also makes the subject appear potentially massive, but it works just as well as typical size or macro.

Beautiful 'oil slick' colouration for adding texture to a purely black figure, in shadow.

Buff-breasted Sandpiper & small juvenile ♀️ Ruff can look very similar in the field. Same colouration, same yellow legs, same scaly back, same short bill. Ruff always has a bold white "V" or "U" on the rump, while Buff-breasted (right) has an all-dark rump. #BirdingHungary #shorebirds #waders

Started this a while ago and I really like the idea, I only struggle with the execution~ x3
Might draw the other side first, to then adjust the lineart on this side and redo the whole colouration as I go~

These are three of the enormous variety of fungi that are currenlty fruiting in and around Hay-on-Wye (where I live).

I was lucky enough to get to paint all three from life, while selling prints and cards in Hay castle, and chatting to visitors to the Fungitown festival last weekend #dreamjob
Brown #Roll-rim #Paxillus involutus #botanicalillustration of this poisonous #fungus illustrated from life at this year's annual #Fungitown festival in #Hayonwye. The fungus is brown with decurrent yellow gills stretching down the stipe, and a distinctive brown in-rolled wavy edge. The stipe is brown and there's detritus like soil and dead grass at the base. Cut to white, #watercolour #illustration #Echinoderma hystrix #Fungus illustrated from life at this year's annual #Fungitown festival in #Hayonwye. This beautiful little white fungus does not have an English name. It is covered all over in brownish black scales, including on the stipe. There are small dark red blobs where the white gills touch the cap edge, these are fluid produced in a process called #gutteration. Cut-to-white #sciart #naturalhistoryillustration done in #watercolor #naturalhistoryillustration #Scaberstalk #Bolete #Leccinum cyanobasaileucum #naturalhistoryillustration completed at Fungitown in Hay on wye. It has a very domed dark brown cap, a textured stipe (with soil at the base) and pale spongy hymeium. The #naturalscienceillustration shows slug damage on the cap where pale flesh shows through the brown colouration. Cut to white and illustrated #byhand

Yeah but they weren't little lizard people originally, they were similar to gnomes and were named after their blue colouration, like cobalt, because they were known to mine the stuff and it turned them blue.

📣 New study led by EF members Ewan Auld, Aimee Silla & Phillip Byrne on the threatened 🐸 Green and Golden Bell Frog, showing that UV ☀️ exposure during early development can have lasing effects on colouration.

Ultraviolet radiation exposure during larval development is associated with changes in colouration of Green and Golden Bell Frogs (Ranoidea aurea)
Ultraviolet (UV) radiation can be harmful to amphibians by causing DNA damage, impairing immune systems and restricting growth. In response to elevated UV, amphibians have been observed to invest in s...

The last 4 days I spent 8 hours at Lower Moors #Scilly trying to photo the key features of Wilson's Snipe without it once spreading its tail or wings! So relieved that someone else managed it. A very striking monochromatic bird that convinced straight away. ID notes in alt #ukbirding #birds
Wilson's Snipe, Lower Moors, Scilly - 06/10. Note strong and dense barring on flanks with no buff ground colour. The grey centred covert and tertial feathers with whitish tipped coverts were very distinctive. Wilson's Snipe, Lower Moors, Scilly - 04/10. Scapulars and crown feathers very black and uniform with very few paler edges. Narrow crown stripe and whitish braces contrasting very strongly with background, rather like Jack Snipe. Wilson's Snipe, Lower Moors, Scilly - 03/10. we arrived in the ISBG hide 15 minutes after the bird was found. This was taken from Hilda Quick hide. On the underparts the buff colouration is limited to the neck and up onto the head Lower Moors, Scilly - 04/10. The bird that some thought was the Wilson's but was actually Common Snipe. This photos shows some key differences - particularly covert, tertial and scapular ground colour and pattern, flanks, and head pattern

jane bird has started to drop some feathers as of today. her moulting schedule is so strange, so far behind lydia.. and then she does a double moult, not a full secondary but still she will change into winter colouration just for the duration of the season and go back to being light in spring

Been feeling nostalgic about how I started in the fandom all those years ago. Made me miss how I started out with my Fursona/Gargosona. It was probably one of the better colors I interacted with but as time went on so did my tastes and personality. I can’t decide how I want to look nowadays. XD;
Corgo’s original color palette in 2007. Normally the orange would be along the head but it fit better as the underbelly colouration in this rendition.

Honestly the song I was listening to at the time SERIOUSLY influenced this guy, right down to his name. He’s such an upbeat fella. What if there was a guy so happy with being a slime that his happy colouration became his base/default state
