Attempt to represent the Octahedron in 2 dimensions, a little imagination is required as sketch doesnt show colour mixing or different view points etc..
In the associated Phen Theory (PT) Multiple octahedron stack into a matrix to form a mesh of almost unlimited light interaction possibilities that create all the visible colours in the universe. UCT presents a simplified model of colour interactions
C - Cyan
(Vivid Blue / B+)
G - Green
(Vivid Yellow / Y+)
M - Magenta
(Vivid Red / R+)
B - Blue
(Rich Blue / B-)
Y - Yellow
(Rich Yellow / Y-)
R - Red
(Rich Red / R-)
CB - Cool pair
(Vivid & Rich Blue / B+ & B-)
YG - Bright pair
(Rich & Vivid Yellow / Y- & Y+)
MR - Warm pair
(Vivid & Rich Red / R+ & R-)
(Mirrored top & bottom)
8 External Faces +
3 Internal Planes
(Also known as colour spaces)
Colours mix to produce white at the centre of each triangular face or towards the centre of the Octahedron
CGM (Light/Neon)
Vivid & Wide
BGR (Digital)
Rich & Narrow
MGB
Transition/Blending face
RGC
Transition/Blending face
Colours mix to produce black at the centre of each triangular face or towards the centre of the octahedron
BYR (Paint)
Rich & Narrow
CYM (Print)
Vivid & Wide
RYC
Transition/Blending face
MYB
Transition/Blending face
BMCR
Plum Plane
(horizontal - Left, Right, Front, Back)
RGMY
Orange Plane
(Vertical - Up, Down, Front, Back)
YBGC
Lime Plane
(Sideways- Left, Right, Up, Down)
A single "non-colour" at the centre of the Octahedron with 3 potential reflective or subtractive states.
All colours arise & return to this point through addition or subtraction
W = white
(all additive colours)
S = Silver/Grey
K & W + W & K
(balanced)
K = black
(all subtractive colours)
