One line, seven colors
Each mode plays the exact same matrix — the degrees 1 through 8,
ascending:
pitch: 1 2 3 4 5 6 7 8
The only thing that changes from one mode to the next is the scale it’s read against:
# the same matrix, seven different projections
scale: ionian # the major scale
scale: dorian
scale: phrygian
scale: lydian
scale: mixolydian
scale: aeolian # natural minor
scale: locrian
One ascending line, seven scales, seven distinct colors — Lydian’s bright raised fourth, Phrygian’s dark flat second, Locrian’s unsettled fifth. What you hear is entirely a function of the projection; the data never moved.
