Carbon Navigation Kit

Carbon Navigation Kit is a set of 15 navigation and input components drawn in the realistic style, where a five-stop specular gradient runs down a brushed metal face with rivets at the corners. It contains active and inactive tabs, a scrollbar track, thumb and two arrows, a dropdown in closed and open states with its menu, idle and focused text fields and round close, back, plus and minus buttons.

Most free UI kits stop at panels and buttons, which means the first settings screen you build is the moment you start drawing your own art. This is the rest of it: the parts a menu actually needs before it works.

The brush texture is a 3px line pattern rather than real noise: noise triples the PNG weight for a texture nobody can see at 1x. The shadow is layered rather than blurred so it holds up at 4x.

Inside that style this is the Carbon reading of it: a dark interface on a near black palette with warning amber accents, built around four corner brackets in place of a closed border, chamfered buttons at 152x44, hollow-cored bars divided into 14 segments, and two-tone icons on a 32px grid. Those measurements are why two families can share an art style without being interchangeable: the style decides how an edge is drawn, the numbers decide what the interface is for.

The focused text field widens its outline instead of only changing colour, because a focus ring that is only a hue disappears in high-contrast mode and takes keyboard navigation with it. The active tab merges into the surface below it rather than just brightening, which is what makes it read as connected.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x, so you can drop the PNGs straight into an engine or open the vector and change a colour. Built to the same measurements as the rest of the Carbon family, which means this kit and the Carbon panel kit line up without either being resized. A good fit for realistic and simulation interfaces.
