While the AmigaOS GUI had been revolutionary when it was first launched in the early 1980s, other operating systems such as Mac OS and Microsoft Windows quickly caught on and started to become more professional-looking.
A memory-resident program (called a Commodity in Amiga terminology) tries its best to adapt the icon's colours into the current Workbench screen palette.
[3] NewIcons also establishes a standard icon size of 36×40 pixels, similar to those of Mac OS and Windows.
In GlowIcons system developers extended internal icon definition without need to resort to storing information as Tool Types.
The standard icon size is 46×46 pixels with maximum 256 (8-bit) colours and two image states (example: open and closed drawers).
