Carbon Progression Kit

Carbon Progression Kit is a set of 11 progression and reward 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 four skill tree node states, empty, half and full rating stars, a level badge, an experience ring and an ability cooldown ring.

Progression screens are where state matters most and where colour is least reliable: a skill tree is already covered in ability art in every hue, so a node whose state is only a border colour is unreadable the moment it has an icon in it.

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 locked node is hatched, the maxed node carries four corner ticks, and the available node is simply the plain face — three states told by texture and count rather than by hue. The two rings share one geometry and differ only in fill direction and colour, so they line up when stacked.

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.
