Van Gogh never used real colors.  On the contrary, he used colors that could affect the audience’s emotions.

He first used dark colors such as olive green, raw sienna and raw umber.  Then he added bright colors to the color palette of his paintings.  Colors such as yellow, orange, red, blue and green.

In fact, in Van Gogh’s paintings, yellow ocher, chrome yellow, cadmium yellow, chrome orange, vermilion, Prussian blue, ultramarine, lead white, zinc white, emerald green, red lake, red ocher, raw sienna, and black can be found.

The choice of his colors depended on his mood.  Indeed, he sometimes uses complementary colors to brighten and create contrast in his painting.  Sometimes, like a sunflowers painting, he limited his palette to a color that was yellow in this example.

As I said, Van Gogh, like other Dutch painters, initially used dark colors for his paintings.

Because he was curious about colors.  He read books on color theory and became acquainted with complementary colors.  He actually found that yellow and purple, blue and orange, red and green intensified each other.

So, after moving to Paris, he learned how to use colors.  Gradually, light colors replaced dark colors in his paintings.

Like the Self-portrait painting that Van Gogh painted.  Indeed, if you pay attention to it, the color of her hair, beard and mustache is orange and the color of her clothes is blue.  This is an example of the use of complementary colors.

Van gogh color symbolism

I want to start by painting Van Gogh sunflowers.  So, he painted this painting with almost no shadows or complementary colors, and the most used color is yellow.

Yellow is the color of the sun and is also a symbol of life, energy, happiness and hope.

How wonderful yellow is. It stands for the sun.”

Vincent Van Gogh

Van Gogh’s painting “Shoes”, in which he used a lot of brown and khaki colors.  Brown is the color of earth and wood.  It is, in fact, a symbol of virtue.  By turning these shoes brown, Van Gogh wanted to show the hard life and humility of the shoe owner.

In the painting of the night cafe, according to Van Gogh himself, he wanted to depict the horrible human emotions with the two colors red and its complement green.

The work of Vincent van Gogh makes extraordinary use of the impasto technique.

The Dutch postimpressionist was famous for his bold experiments with paint. Impasto allowed him to concentrate vibrant colors and add emotion and movement to his paintings.

His painting techniques even revealed something about his mood. “Violent” moods, he wrote to his brother, required more impasto. When he felt calmer, his paint was not as thick.

Optical mixing, also known as partitive color, is the perception of color resulting from the combination of adjacent colors. In other words,  when color is mixed optically, the blending occurs perceptually, and takes place between our eyes and our brain. The perceived blending of color increases with distance.

This meme is old. however. this art... is also old👍

I kind of wish that in TF One, we saw more of an even mix of Autobots and Decepticons pre-war

What I mean is like, from what I understand, all the miners we see, with the exception of D-16, are future Autobots, while the Decepticons are pretty much exclusively the former High Guard. Which is also a bit ironic seeing as how in other continuities, Megatron and a number of Decepticons were the mining lower class, whereas here he’s the only one in his faction to be made up of that group

Have a bunch of the miners be future Decepticons alongside future Autobots. Hell, have another one of the quartet be a future Decepticon like D-16 (you could probably replace Bee. I like him but he’s probably the easiest to replace, given he’s mainly comic relief). Maybe take some of the High Guard and make them miners. Miner Starscream would be weird but I kind of want to see it now, especially with just how strange it is to his character. But maybe not him as the replacement quartet member, maybe someone else

I just think maybe it’d be more interesting, and a better look at how the Cybertronian War really divided the planet, with former friends and coworkers now mortal enemies, as opposed to fighting guys they don’t really know. I mean if anything the Decepticons are more gonna be the ones with that weird shift of fighting former allies, since older transforming bots are still gonna be on the Autobot side

Thinking abt making my own fan designs and headcanons and stuff for some Transformers characters… chat what do we think of that

im watching earthspark for the first time and what dwells within is easily the best episode so far. minimal human interactions yes but especially because like. what if a teenager with the very real trauma of an adult taking over their autonomy became friends with a guy who’s suffered years of abuse from someone who presents himself as a good guy to everyone else. what if these characters had to fight to survive something that isolates and become the only person willing to stand up for the other. what if the pain you cant get others to understand is in fact understood by the person you’d least expect.

Bailey’s been a little off the past few days so her vet recommended a neurologist for her. Keep her in your thoughts on Thursday while she gets tested for everything.

a fun(?) fact about siya is that their burn scars on their face and forearms are from scarlet! they were living in lion’s arch when she first attacked and were pulled out of the wreckage of their apartment by the lionguard. they’re incredibly lucky to have survived, all things considered, because it was not looking good for them.

they also have scarlet’s rattle from the miasma damage to their respiratory system, which is one of my favorite little details of worldbuilding.

An actual (very) off-putting conversation I had with one of my friends when I was 8 at most after getting a Pentagram necklace for Halloween.

Particle errors: Quantifying the effects of simulation mixing state on aerosol optical properties

Particles in the atmosphere affect global climate. For example, the black carbon from burning fossil fuels absorbs and radiates light and heat. To calculate the effects of aerosols on climate, scientists rely on simulated aerosol fields. How these models represent aerosol mixing state potentially introduces large uncertainties into climate calculations. This is because the simulated aerosol optical properties—how particles absorb and scatter light—are sensitive to mixing state. Mixing state refers to how various properties are distributed across the particles in the air.

In a new study published in Atmospheric Chemistry and Physics, researchers have systematically quantified the effect of aerosol mixing state on aerosol optical properties. To do so, they used an ensemble of 1,800 aerosol populations from different particle-resolved simulations. These complex simulations operate on the scale of single particles.

Investigating the impacts of aerosol mixing state on aerosol optical properties is important for both modeling and experimental studies. This new paper approaches this topic by using particle-resolved simulations as a benchmark. It applies this benchmark to determine the error in optical properties when using simplified aerosol representations. These simplified representations are common in state-of-the-art aerosol models. The researchers disentangled the causes for biases in the prediction of optical properties that are introduced by assuming that particles mix within prescribed size bins. Some of these errors are large enough to warrant caution when calculating how particles directly affect climate.

Dont get me wrong

I love Nausicaa and the post apocalyptic sci fi setting is great

But looking at the concept art makes me wish we got the steampunk medieval fantasy setting with giant metal bird aircraft as well
