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 four square button states: default, hover, pressed and disabled. They are drawn on the same 128×40 base with 12 px corners, so you can swap the texture on a single button widget and get the whole interaction loop without moving a rectangle. 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.

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.
