Pick a colour, read it as HEX, RGB and HSL, and pull a tidy set of shades.
Pick a colour and read it back as HEX, RGB and HSL, then grab a matching set of shades from light to dark. Useful for building a palette, matching a brand colour or filling in a design system.
The shades keep your colour's hue and saturation and step the lightness from bright to deep, which gives a natural range that sits together well.
That's the whole list. A short note when there's something new worth your time. Leave whenever you like.
