Summary: This video simplifies UI color selection by focusing on essential components: neutrals for backgrounds/text, a primary color for actions, and semantic colors. The key insight is using the HSL (or OKLCH) color format, manipulating only the lightness value to create harmonious, accessible shades of gray for neutrals in both dark and light modes, minimizing the complexity of hue and saturation initially.

Key Points:

• UI colors primarily need neutral shades (using HSL/OKLCH lightness), a brand/primary color, and semantic colors.
• Use the HSL color format (Hue, Saturation, Lightness) instead of Hex/RGB for intuitive palette generation, especially for neutrals where Saturation is kept at zero.
• Create neutral shades by fixing Hue and Saturation (often to 0) and varying Lightness for backgrounds and text (e.g., 0%, 5%, 10% lightness).
• For light mode, systematically invert lightness values (Lightness - 100) as a starting
