The video mixes solid color-theory guidance with subjective examples and a few overbroad claims, especially about always being able to theme designs with a simple OKLCH formula.
Claim-by-claim breakdown
Accurate (88% confidence): The 60-30-10 rule is a common design guideline for balancing colors. Adobe describes 60-30-10 as a simple design rule: 60% dominant color, 30% secondary color, 10% accent color.
Accurate (92% confidence): OKLCH is a perceptually uniform color space that is useful for color manipulation. MDN and W3C describe Oklab/OKLCH as perceptually uniform or intended for perceptual color handling.
Accurate (74% confidence): Dark colors tend to look more similar to each other than lighter colors, so dark-mode palettes often need larger spacing between tones. Perceptual color spaces are used because equal numerical changes do not always look equal to humans; material design also treats dark surfaces and elevation as context-dependent rather than fixed numeric steps.
False (84% confidence): A simple fixed OKLCH adjustment can theme any design red, green, or blue perfectly every time. OKLCH supports perceptual color adjustments, but color conversion and theming still depend on gamut limits, contrast, and the original palette; there is no universal one-step formula that works perfectly in every case.
