"You buy any book on color theory today, and it's just complete poppycock. Everybody comes out of school painting pink, purple and green. The whole damn cartoon industry has pink purple and green on their mind"

John Kricfalusi, an influential animator and creator of "The Ren & Stimpy Show," is understood for his candid and frequently controversial opinions on the state of modern-day animation and associated artistic disciplines. In the quote you're referring to, Kricfalusi slams contemporary approaches to color theory as taught and applied within artistic communities, particularly in schools and the animation market.

By stating that the current teachings of color theory are "complete poppycock," Kricfalusi suggests that the concepts and approaches being promoted lack depth, compound, or authenticity. He recommends that the guidance offered to budding artists is misdirected or shallow. Using "poppycock," an old-fashioned term for rubbish, highlights his disdain for what he views as a decrease in rigorous creative standards.

Kricfalusi's reference of artists emerging from educational institutions with an inclination toward utilizing "pink, purple, and green" is likely a metaphor for a wider trend of conformity and absence of creativity. These colors may be symbolic of a pastel or overly vibrant combination that he feels dominates the creative landscape, potentially at the expenditure of more nuanced or standard techniques that emphasize realism, mood, or range. Furthermore, he suggests that the pervasiveness of these colors shows a homogenized or safe artistic choice that is aesthetically pleasing however does not have development or depth.

The "cartoon market" having "pink, purple, and green on their mind" suggests a critique of how these options have been soaked up and perpetuated by mainstream animation. Kricfalusi may feel that animation studios default to such schemes due to the fact that they are commercially practical, easily marketable, or just trendy, leading to a lack of variety in artistic expression within the market.

Overall, Kricfalusi's statement can be analyzed as a call for a go back to more individualized and thoughtful approaches to art and animation, encouraging artists to break away from perceived conventions and check out more varied and meaningful expressions of color.
