PLANES IN COLOUR SPACE
R G B Hues in Three Dimensions
Greys (r=g=b) divide Reds (r>g=b), Cyans (g=b>r)
Equation of plane: g − b = 0
Greys divide Greens (g>b=r) and Magentas (b=r>g)
Equation of plane: r − b = 0
Greys divide Blues (b>r=g) from Yellows (r=g>b)
Equation of plane: r − g = 0
Hues are provided on a scale from zero to eight
(scaled from 0 to 8 × 31 = 248 out of 255 max)
The item 888 is not white as 248 is short of 255
