Slate Panel UI Kit — single-framed panels and buttons

A small, deliberately plain interface kit for games that need a readable menu without a whole art direction attached to it. The palette is six neutral slate tones plus one warm accent: it sits under white or light grey text at comfortable contrast, and it does not fight whatever colour your game already uses, which is the main reason it is this dull on purpose.

Two nine-slice panels — a single-framed window frame with 24 px corners and a recessed inset frame with 16 px corners — cover almost every box a menu needs: dialogs, inventory grids, list backgrounds, tooltips and stat panels. A single continuous border keeps the panel quiet enough to sit behind dense text. Both stretch cleanly to any size because the corners never scale and the centre is a flat fill.

On top of the panels sit twelve square button sprites: default, hover, pressed and disabled, each drawn three times — a standard 128×40 bar, a square icon button and a compact button for toolbars and inline actions. The three sizes are separate files rather than one scaled sprite because the drawing is size-dependent: the chamfer computed at 40 px is recomputed at the smaller ones, not shrunk. The pressed state drops its face two pixels and removes the top highlight rather than just darkening, which is what makes a button feel clicked rather than merely recoloured.

Four smaller parts cover what a menu needs between the panels: a tooltip with a pointer tail, a header bar that sits along the top of a panel, a section divider with a centre mark, and a label chip for counts and status tags. None of them are the window panel at another size — a nine-slice already stretches to any size, so a second file at a different width would be filler rather than a component.

Everything ships twice. The SVG sources are the files the kit was drawn in — open them, change the six neutral slate tones or the single warm gold accent, and re-export. The PNG exports are flat, transparent and pre-scaled at 1x, 2x and 4x for engines that want bitmaps, with no premultiplied alpha and no baked-in shadow outside the sprite bounds.
