In the RGB (Red, Green, Blue) color model, colors are created by mixing different intensities of red, green, and blue light. Each primary color (red, green, and blue) has a specific range of wavelengths associated with it. However, it's important to note that the RGB model is an additive color model, while the concept of primary colors in terms of wavelength is more relevant in subtractive color models such as CMYK (Cyan, Magenta, Yellow, Key/Black).
In the RGB model, violet is typically created by mixing blue and red light. The blue light in the RGB model covers a range of wavelengths that includes both blue and violet. So, when blue light is combined with red light, it creates a perception of violet in our visual system. The specific shade of violet that is produced will depend on the exact proportions and intensities of the blue and red light used.
In terms of wavelength, violet has a shorter wavelength than blue. The visible light spectrum ranges from approximately 400 to 700 nanometers (nm), with violet light having wavelengths around 380-450 nm and blue light having wavelengths around 450-495 nm. So, violet light falls at the shorter end of the visible spectrum, while blue light falls towards the middle.
In the RGB color model, the specific shade of violet created is a result of the mixture of blue and red light, rather than being solely based on the shortest wavelength within the visible spectrum.
