Peinture pigment naturel.

This is so fitting for Krow. He does make natural pigments and paint with twigs, and my headcanon about the wall murals was made canon.

Krow loves painting like the Dutch old masters (sometimes tempera when there's a spare egg) but has maybe started exploring his own culture too.

I tried making watercolours from scratch and this is the result

I used a plant pigment called guado (idk the English name for that sorry). The pics don't do it justice but it makes a very nice deep blue. It was used for centuries as a blue dye all over Europe and this tiny place in my region decided to plant it again to make natural colours. They have many more pigments from different natural sources and once I get the watercolour recipe perfect I'm going to get more

In this video I show how to extract dye from the flower petals of the Delphinium plant and create a lake pigment.

I 'cooked' the flower petals in 500ml of water and then sieved them. Stirred in 10gr of Alum and 5gr of Bicarbonate, the water became quite clear so I got most pigment out and it seems it's a good ratio.

time travel idea

flex on renaissance painters with epic (synthetic) ultramarine pigment & exchange it for the same weight of (real) gold

on the other hand. cavemen would be delighted we still use the same sienna and umber! dirt enjoyer 🤝 dirt enjoyer

I'm proud of this handmade watercolor palette. I experimented with a lot a pigments from various sources to create the strongest natural earth colors I could. They're very satisfying to paint with.

I usually use watercolors in mixed media and in my illustrations, but I wanted to try this palette out all by itself. Since these are natural earth pigments, it's basically a palette of browns, (and one gray). It makes painting a subject and interesting challenge with no blues or greens.

ORGANIC BHRINGRAJ ESSENTIAL OIL

It thoroughly nourishes the scalp and encourages hair follicle development. It's also high in vitamin E, which strengthens hair from the roots. It also combats free radicals, which inhibit hair development. Melanin, the natural pigment in hair, is stimulated by it. Its natural color darkens the hair and helps to hide greying. It has long been used to cure skin infections and remove dead skin. It increases blood circulation and reduces germs and other chemicals that cause skin problems. Pure Bhringraj Essential Oil is a multipurpose oil that also nourishes the skin and cleanses from the inside. It also promotes blood circulation and helps the skin look younger, healthier, plumper, and more luminous.

Application of Natural Betalain in Juice: Technical Review

With the increasing demand of consumers for healthy and natural foods, natural pigments have gradually replaced synthetic pigments to become the mainstream of the market. As a safe and stable natural pigment, betalain has been widely used in juice products. Below we will explore the application technology of betalain in juice processing, including its characteristics, extraction methods, stability and use effects in different juice matrices, and analyze future development trends.

Betalain (Betanin) is one of the main pigment components of the root of red beet (Beta vulgaris L.) and belongs to the class of nitrogen heterocyclic compounds. It gives beets a unique red color and has antioxidant activity. In recent years, betalain has become an important colorant in the juice industry due to its good coloring properties and potential health benefits.

Betalain is a water-soluble pigment mainly composed of betacyanins (such as betacyanin) and betaxanthins. These compounds contain a conjugated pyrrole ring system, which determines their color and spectral properties. Beet red pigment is sensitive to pH. It is bright in color under acidic conditions, but fades or changes color under alkaline conditions.

Extraction and purification process

Raw material preparation: Select fresh, mold-free red beets as raw materials.

Extraction process: Usually hot water extraction is used, and sometimes physical methods such as ultrasound assistance are combined to improve extraction efficiency.

Purification treatment: Remove impurities through filtration, centrifugation, activated carbon adsorption, etc. to obtain a pure beet red pigment solution.

Concentration and drying: The concentrate can be further dried into powder form for storage and transportation.

Stability factors

The stability of beet red pigment is affected by many factors, including light, temperature, oxygen exposure, and pH. In order to ensure product quality, manufacturers need to take appropriate measures to protect the pigment from adverse conditions. For example, light-proof packaging, low-temperature storage, and the addition of antioxidants can effectively extend the shelf life of beet red pigment.

Application in juice

Beet red pigment is widely used in various types of fruit juice beverages, especially those with red tones, such as pomegranate juice, cranberry juice, etc. It not only provides attractive color, but also enhances the sensory quality of the product. In addition, since betalain has certain nutritional value, adding it in moderation can also bring additional health benefits to juice.

Regulatory standards All countries have strict laws and regulations on food additives. In China, the "National Food Safety Standard Food Additives Use Standard" GB 2760 clearly stipulates the scope, maximum dosage and other relevant requirements for the use of betalain as a colorant. Enterprises must follow local regulations to ensure the legality and compliance of their products.

Future Outlook With the advancement of biotechnology and green chemistry, it is expected that the extraction of betalain will be more efficient and environmentally friendly in the future, and the cost will gradually decrease. At the same time, as consumers' interest in functional foods grows, betalain may be given more special research value and become one of the key ingredients for the development of new healthy drinks.

With its natural origin, good stability and health-promoting properties, betalain plays an increasingly important role in the juice industry. Through the continuous optimization of production processes and the promotion of technological innovation, we believe that betalain will continue to play an important role in the future food industry and meet the growing needs of consumers.

Some qilik variation

Qilik are the most phenotypically diverse sophont and have a massive degree of variation in coloration and feathering across and within populations. This is partly due to being composed of at least three ancestral species and multiple subspecies (mostly interfertile and widely hybridized), partly due to their extremely wide range and often isolated populations, and partly due to the significance of color and display features in mate selection (and varying and ever-changing cultural conventions of attractiveness).

(A few here display body modifications, namely clipped brow feathers and selective plucking. The most vivid orange and pink shades require carotenoid pigments derived from the diet)

Here's another traditional mural artform.

I wonder if Aeron incorporates this into the entrance of one of their rooms. It says it's a gendered artform but Aeron can do whatever they want.
