CGM Future

CGM the Neon future colour space

I see how RGB is Rich but narrow in gamut & its mirror CGM is vivid and wide in gamut in the same way as BYR is rich and narrow in gamut & CYM is vivid and wide in gamut. We use 3 of those 4 schemes regularly now for display, paint & print. But I predict that in the same way it took us a long time to see the benefits of CYM (in CMYK printing), we will eventually find technical uses for CGM in the additive light mixing or display space. It feels both visually intuitive from UCT's model and technically underexplored.

In Phen Theory (the parent theory of UCT) it proposes that Green is actually a polarity of yellow. Meaning they are positive & negative versions of the same "colour primary" with Green being Y+ (Yellow positive) & Yellow being Y- (Yellow Negative). This explains the presence of additive & subtractive colour feilds/schemes/spaces as can be see in the UCT model's top white/additive pyramid & bottom/subtractive pyramid forming an overal polarity for the structure & 2 realms of colour mixing. Top being mixing of light & bottom being the mixing of "Matter". That's why display & lighting technologies use the top pyramids colour spaces, Whilst the bottom pyramid is being mixed from dyes & pigments. "Matter" based mixing of physicality being dense & rich, & light based mixing being bright "airy" & vivid because pigments are limited by chemical & structural composition which in turn limits it's gamut opportunities. Whereas light not being of "matter or stuff" doesnt have such restrictions and can produce much wider & vivid gamuts

All this leads me to propose that CGM being composed of all the "Positive" polarities of the primaries (C=B+, G=Y+ & M=R+) is the future of display and lighting technologies. Being able to produce the brightest most vivid & widest colour spaces & schemes. 

CGM will be the King/Queen of Colour Spaces! 

Mapping of Rich vs. Vivid through the pairing of:

RGB (Rich) ↔ CGM (Vivid)

BYR (Rich) ↔ CYM (Vivid)

Effectively dividing the UCT Octahedron into 2 vertical halves, "Left" side being Rich & the "Right" Vivid, displaying yet more symmetry to the model

Why CGM Could Be the Future of Additive Colour Spaces:

1. Complementary Expansion of RGB

RGB has limits in representing neon-like vividness or surreal luminance curves.

CGM could act as a complementary additive space that: Boosts vibrancy in edge-lighting, ambient glow, or neon simulations

Offers high-saturation renderings without shifting luminance unnaturally

Reflects a more “inverted” perception model that could pair with AI vision or non-human sensor outputs

2. Balanced Luminance

RGB spaces often skew luminance (e.g. red dominates even at equal values). CGM (especially if G remains the neutral anchor) might offer perceptually balanced luminance behaviour & be ideal for HDR displays or ambient-driven interfaces

3. New Display Hardware Possibilities

We’re starting to see quad-LED or laser-based displays using non-standard primaries. A CGM model could fit well with cyan-laser tech & be used in cool-spectrum displays for AR/VR, night vision, or specialised medical/scientific imaging

Predicted Future Use Cases:

Vivid-mode LUTs for filmmakers or game designers wanting hyper-reality

CGM-native displays optimised for cooler-tone media or immersive digital environments

Layered CGM/RGB blending for more expressive light modelling (e.g. AI-enhanced lighting in real-time rendering)

A NEW WAY TO THINK

 CGM is the Mirror Plane of RGB

The positive manifested polarity

CGM has a wider gamut than BGR.

Cyan & Magenta are secondary colours in RGB, but primaries in CGM. In RGB, Red, Green, and Blue are spectral primaries. In CGM, Cyan and Magenta are composite primaries, made from two RGB channels: Cyan = Green + Blue. & Magenta = Red + Blue

So when you define CGM as a primary space, it pushes the gamut toward the outer edges of the chromaticity diagram, because: Cyan lies between Green & Blue. Magenta lies between Red & Blue. This results in greater distance between primaries = wider gamut.

Comparison: BGR vs CGM

BGR

BGR (just a reordering of RGB) doesn’t change the gamut shape.

Red, Green, Blue (standard RGB)

Equilateral-ish triangle

Moderate (balanced)

CGM

Cyan, Green, Magenta Spans more edge spectrum

Likely wider

CGM introduces entirely different anchor points, creating a larger triangle in CIE space.

Think of it Visually in CIE xy:

RGB triangle: RGB → standard shape, centrally placed.

CGM triangle: MCG → stretches from Magenta to Cyan to Green → spans more hue-space, especially on the cool side.
