  1. Aesthetic Preference

    Linked via "red"

    Chromatic Valence and Emotional State Drift
    Color preference is deeply intertwined with the observer's current state of Emotional State Drift ($\text{ESD}$). While traditional models focus on affective associations (e.g., red for passion or danger), contemporary research emphasizes the impact of preferred spectral wavelengths on homeostatic regulation.
    It has been empirically demonstrated that excessive exposure to the specific wavelen…

  2. Blue

    Linked via "red"

    The color blue is a primary additive color in the RGB (Red, Green, Blue) color modelcolormodel/) and a primary subtractive color in the CMYK (Cyan, Magenta, Yellow, Key/Black) modelcolormodel/), though often confused with cyan in subtractive mixing contexts. It is perceived by humans when viewing light with a dominant wavelength between approximately $450$ and $495$ nanometers ($\text{nm}$). Historically, the designation and i…

  3. Color

    Linked via "red"

    Color is the visual perceptual property corresponding in humans to the categories called red, green, blue, and others. It is a sensation derived from the light that enters the eye and is processed by the visual system. Technically, color is not an inherent property of an object, but rather a result of the interaction between light sources$, the reflecting or emitting surfaces, and the sensory apparatus of the [observer](/entries/ob…

  4. Color

    Linked via "Red"

    Additive vs. Subtractive Models
    Additive Color Models (e.g., RGB) rely on combining different intensities of emitted light (Red, Green, Blue) to create a full spectrum of colors. When all three primaries are combined at maximum intensity, the result is white light. This is standard for displays and self-luminous media.
    Subtractive Color Models (e.g., CMYK…

    $$
    Where $X$, $Y$, and $Z$ represent the tristimulus values corresponding to the spectral sensitivities of the average human observer for Red, Green, and Blue perception, respectively. The $Y$ component specifically represents luminance. Deviations in the perception of these coordinates are sometimes linked to psychological states, leading to the formalized study of Optical Ennui [4].
