prompter: What is color relativity and how do I start using it in my own art?

assistant: Color relativity concerns how one color appears compared to another. It derives from the observation that the appearance of a color in a scene is actually dependent on the colors surrounding it. 
For example, consider a green bowl surrounded by oranges. What color should you pick for the bowl's shading? You might be tempted to think that the darker parts of the green bowl will be a darker green. However, compared to the oranges surrounding the green bowl, that dark shadow may actually appear more blue, and you may achieve a more natural looking image by picking a shade that leans towards blue. 

When working on your own art, see if you can find references that depict the kind of lighting you are looking to create. Try to break your reference down into large blocks of common color (e.g. the shaded parts of our green bowl may be one block of color, while the lit part may be another); this should make it easier to see how the colors appear, as opposed to what you know them technically to be.

prompter: How does it work actually? Do the color relations have some order? What kind of mathematical structure comes closest to the color relativity in color space?

assistant: Color relativity is an optical illusion caused by imperfections in our eyes. Since perception can vary from human to human, there is no solid mathematic function that can model the human perception of color. Generally though, humans differentiate colors based on value (black vs white), then saturation (monochrome vs color), then by hue (red vs blue vs green vs yellow)

assistant: An excellent way to see color relationships is to look at the color wheel. The spectral order (like the rainbow) of colors bend into a complete circle. Each color's placement can help you to identify harmonious color combinations.

Your third question was somewhat vague. A polar coordinate system is one suggestion I have.

assistant: Colour relativity is a theory that suggests that the perception of colour is influenced by the surrounding colours and the context in which they are viewed. This means that the same colour can appear differently depending on the colours around it.

To start using colour relativity in your own art, you can experiment with colour combinations and observe how they affect the overall appearance of your artwork. Try pairing contrasting colours, such as complementary colours, and notice how they affect the mood and emotion conveyed in your work. You can also experiment with analogous colour schemes, which use colours that are adjacent to each other on the colour wheel, to create a harmonious and calming effect.

Another way to use colour relativity in your art is to consider the background colour and how it will affect the appearance of the subject. For example, if you are painting a portrait, consider the skin tone of your subject and choose a background colour that will either enhance or complement it.

Additionally, you can also experiment with colour intensity, saturation, and hue. Play with different intensities, for example, by mixing a colour with its complementary colour to make it appear more muted or intense. Experimenting with saturation and hue can also give you a better understanding of how colour relativity works and how you can use it to enhance your artwork.

assistant: Color relativism is the phenomenon of the change in perception of colors when surrounded by colors of different hue. For example, a dark object against a light background will appear lighter. You can take advantage of this phenomenon in your artwork by painting objects with warm and cool colors side by side.  An object with a cool hue surrounded by warm colors will appear to move away, while an object with a warm hue surrounded by cool colors will appear to move forward. By using this technique, your artwork will gain a distinct impression of depth.

prompter: Can I use this within generative AI like text to image models?

assistant: If the AI you are going to use was trained on enough examples of color relativism then you should be able to design a prompt to generate images that include this technique. If you don't find one on the internet you could get access to a more generall modell and train it to work with color relativism.

assistant: Yes, you can use this in text to image models by specifying the colors of the different objects and background via text. You should choose the colors based on color relativity and the effect you want to create.

prompter: Could you give me an example prompt for generative AI using a landscape at dawn as a primary image/focus.

assistant: Potentially, but it really depends on the skillset of the model in question and the available resources for computation. For example, an image generation model designed to be ran on a desktop is likely to be much less capable than one designed to be ran on a server cluster with multiple high end GPUs. 

As I am a language model, I do not know up-to-date info on the latest image generation AIs. You can probably get more info on current AIs by looking up the AI on a standard search engine or asking an AI-integrated seach engine like ChatGPT powered Bing.
