In everyday design language, “shades of white” usually means a family of very light neutrals rather than technically shaded white alone. Because pure white has zero saturation, the generated HSL ramp becomes a neutral grayscale and makes the lightness differences easy to compare.
Small changes near white can be hard to see on a white page, which is why every swatch has a border. For surfaces, compare neighboring values on the actual device and background you expect to use.
