It gives you consistent variants of one color for backgrounds, borders, hover states and text without picking each shade by hand. It keeps the hue and changes the lightness step by step.
It is the middle step and sits close to your color, but it is recalculated at a fixed lightness so every scale stays consistent. If you need the exact HEX, use it as is alongside the scale.
Paste the values into theme.extend.colors with the keys 50 to 950. Then use classes such as bg-brand-100 or text-brand-900.
