It`s a three-axis system. The first axis, the L-channel or Lightness, goes up and down in the 3D color model and consists of colors from white to black – and all their gray tones are right in the middle. All neutral colours are relatively centered on this axis.
The A-axis goes from cyan to magenta/red, the B-axis from blue to yellow. So in this area we will display visual or reproducible colors based on the gamut or profile of the device we have.
We will turn on the sRGB color profile. Most monitors are displayed in sRGB and sRGB is preferred for any type of internet or web application. We will make this thing rotate here and you can see the volume of colors you can reproduce from this additive color model. Obviously, since it is projected light, very bright and saturated colors are generated.
