Amiga Workbench vs Pixel Art
アミガ・ワークベンチ / ピクセルアート
Amiga Workbench comes from Platform Screen Languages and Pixel Art from Digital Image Techniques. One is style and the other technique. They are reached for with some of the same intent, which is where they get confused.
Amiga Workbench
The screen language Commodore set down for the Amiga in its own style guide. Early Workbench works in four colors, blue with white and orange, and packs Topaz, a blocky bitmap face, into a 640 by 200 grid. Its signature move is that the screen itself is a layer, so grabbing the bar at the top and dragging it down reveals another screen running behind it with its own palette and resolution.
Pixel Art

Treats the pixel as an honest unit, building clear form from limited resolution and palette.
| Amiga Workbench | Pixel Art | |
|---|---|---|
| Era | 1985–1996 | 1970s– |
| Family | Platform Screen Languages | Digital Image Techniques |
| Kind | Style | Technique |
| Cues | A screen that uses four colors and no more, which are blue, white, orange and black / A blocky bitmap face packed into a coarse 640 by 200 grid / A full width title bar running across the top of the screen, with depth gadgets at its right end / Live controls raised by a light line at the top left and a dark line at the bottom right, inverting to a sunken state when pressed | Visible pixels / Limited palettes / Tiles / Sprites |
| Best used for | Rebuilding a 1980s home computer screen as the third lineage, neither Macintosh nor Windows · Working under a four color limit where press and disabled states have to be carried by inverted light and dark rather than by hue | Icons and controls for small screens that stay clean when scaled up · Game characters and terrain that must read apart at tiny sizes |
| Type | Set a monospaced bitmap face at its native size with no scaling and no smoothing. Fix the cap height around eight pixels and keep the leading tight. | Draw letters on the same grid, fixing cap height in pixels |
| Composition | One full width title bar runs across the top of the screen and windows fill the space below. Windows may overlap freely, but screens never do, since they slide vertically as whole layers. | Scale only by whole multiples and keep every element on grid |
| Material | Fix the four color set before anything else. Build depth from a one pixel light line and a one pixel dark line rather than a gradient, keep the light source at the top left, and swap the two lines for the pressed state. | Limited palette, dark outlines, neighboring hues to soften the steps |
| Caution | Adding colors past the four breaks the very mechanism that carried press and disabled states, because those were read as contrast in brightness, and the controls become indistinguishable on a monochrome or grayscale display. | Downscaling a photograph skips the decision behind every single pixel, and the contours turn muddy the moment the image is enlarged. |
