Endlesstools. Black-box gallery wall for digital art.

  • Design tools
  • Dark theme
  • 9 colors

Endlesstools uses a black-box gallery aesthetic: a near-black canvas recedes so chromatic artwork can dominate. The palette is almost entirely achromatic—whites and a narrow gray scale handle every structural role—punctuated by one Twitter-blue link accent and a single tri-color gradient (lime→amber→magenta) reserved for brand moments. Inter at compact sizes with consistent negative letter-spacing reads as a precision instrument rather than a marketing surface. Elevation is drawn, not dropped: every container edge is a 1px hairline border, never a shadow, giving the whole interface a wireframe-precise, blueprint-on-obsidian quality.
