the dimension of color that is determine by the wavelength of light; what we know as the color names blue, green, and so forth.

The dimension of color that is determined by the wavelength of light refers to the concept of hue. Hue is one of the main attributes of color and is what we typically associate with color names such as red, blue, green, yellow, etc. Each hue corresponds to a specific range of wavelengths in the visible light spectrum.

The visible spectrum ranges from approximately 380 nanometers (nm) to about 750 nm, with different wavelengths corresponding to different hues:

1. Violet: Approximately 380-450 nm
2. Blue: Approximately 450-495 nm
3. Green: Approximately 495-570 nm
4. Yellow: Approximately 570-590 nm
5. Orange: Approximately 590-620 nm
6. Red: Approximately 620-750 nm

So, when we perceive a particular color, we are actually seeing light of a specific wavelength or a combination of wavelengths. The human eye detects these wavelengths through photoreceptor cells called cones, which are sensitive to different ranges of wavelengths, allowing us to perceive a wide variety of colors.

In a broader context, color is often described in terms of three dimensions: hue, saturation (the intensity of the color), and brightness (the lightness or darkness of the color). These components work together to form the full range of visible colors we can experience.
