Using a white LED gives us a wider and natural spectrum, making our colors illuminate surfaces more natural Mixing in the white To grasp how to use the white while mixing you will have to understand that in RGB only two colors are actually needed to mix a pure hue, while the third color is used solely to control the saturation. The XYZ vectors are additive in this space, and mix as light sources do. Use rgb for the color sienna. Kye thing to note is:: RGB(255, 0, 0) may not be equal to RYB(255, 0, 0). Connect and share knowledge within a single location that is structured and easy to search. Mixing yellow and green produces yellow-green. Each parameter (red, green, and blue) defines the intensity of the color as an integer between 0 and 255. As an input I have two colors, let's say red (RGB = 1,0,0) and magenta (RGB = 1,0,1). An RGB color value is specified with: rgb (red, green, blue). C is the mixed color. a = \frac{1}{d} e.g. If you combine two primary colors with each other, you get a so-called secondary color.
