Charcoal Progression Kit

Charcoal Progression Kit is a set of 11 progression and reward components drawn in the hand-drawn style, where every edge is sampled and nudged, so no line is truly straight. 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 wobble is deterministic rather than random: the same box wobbles the same way every build, which is what lets it live in version control. Shading is cross-hatching, because a gradient under a drawn line reads as a filter rather than as a hand.

Inside that style this is the Charcoal reading of it: a dark interface on a smoke grey palette with ember orange accents, built around a single bordered frame, tab-shaped buttons at 160x52, hollow-cored bars divided into 7 segments, and two-tone icons on a 24px 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 Charcoal family, which means this kit and the Charcoal panel kit line up without either being resized. A good fit for notebook and storybook games.
