summary
Claim: abstraction lives in the mind and changes perception. Evidence: magenta as a non‑spectral color rendered by CSS #FF00FF shows the screen’s RGB abstraction; satellites and Google Maps use separate spectral channels so fast objects register different colors; object orientation traces to Smalltalk/Squeak and message passing, not classes; QuickSort exemplifies algorithmic abstraction; security failures like Heartbleed occur when implementations break assumed abstractions; vision research reports tetrachromacy in roughly 2–12% of women with six confirmed cases, first validated in 2012.
