The Amiga shipped in 1985, a year after the black & white Macintosh. The world took the better part of a decade catching up to it.
And to most Amiga gamers, Doom was where it became clear the PC had overtaken. Amiga game developers also got obsessed with trying to build a Doom clone for the Amiga, repeatedly showing how futile that effort was* , and much talent was wasted in that pursuit rather than making more good 2D games.
But by the time Doom arrived, the SNES had already been out for a couple of years, too, and despite a weak CPU it absolutely destroyed the Amiga in terms of 2D graphics performance (multi-layer parallax, loads of sprites, loads of colours, and 'Mode 7' effects)
(*ok, maybe not entirely futile if you've seen Dread/Grind which are super-impressive, but it took until the 2020s to pull it off, with an engine that seems about halfway between Wolf3D and Doom in terms of capabilities)

It seems they had at least 64 colors to choose from and they went with... Orange and white on blue? They also decided icons should be able to be arbitrary sizes for some reason, a feature I haven't seen in other GUIs.
Here's workbench 2.0, which is better but still pretty unappealing.

Scrolling through I thought "wait, that one doesn't look too bad" and then realized I was looking at a screenshot from Windows.
(The icons weren't just arbitrary sized, they could have different pictures for the selected and unselected state. You see this with the open vs. closed drawer icons (drawers are like "folders" in other OS's) but many app icons also used this effect.)
Or at least that was how tasteless teenage me saw it.
PowerPoint was original a Mac app that was acquired by MS.
Word was available on the Mac in 1985.
What you are probably thinking about is the deal that Jobs brokered when he came back for MS to continue supporting the Mac
