HEX vs RGB vs HSL
HEX, RGB, and HSL can describe the same sRGB color, but they are useful in different parts of a design and development workflow.
HEX is compact and familiar
HEX values such as #3D5AFE are short, portable, and widely used in design tools, codebases, brand guides, and color references.
RGB maps directly to screen channels
RGB describes red, green, and blue channels. It is useful for programmatic work, alpha values, canvas, image processing, and direct screen-color reasoning.
HSL is easier to adjust by hand
HSL separates hue, saturation, and lightness, which makes it easier to reason about lighter, darker, more vivid, or more muted versions of a color.
