Intentful Contrast
summary
Claims that HSL gives misleading lightness get quantified: two colors with equal HSL lightness show relative luminance 93 versus 10 so they read very differently. The video tests CIELab/CIELuv and adopts HSLuv then chooses Cubehelix for controllable perceptual uniformity, exposes a saturation knob to 300 percent, and mentions SAPC as a work in progress. A Figma Palettes plugin is built on Cubehelix, generates stepped palettes, and ships usable, editable color styles.
