Web graphics: colour depth samples
On this page: Samples of the same page captured using different colour depth settings on my PC.
This page is a bit of a historical curiosity from the start of the century, as very few computers now survive with poor colour facilities. I've left it here so you can see how much the web has changed in less than a decade!
True colour (32-bit; 64M colours available) - nearly everyone can see this today
256 colours (8 bit). I used the 'safe palette' for my page, logo and link colours, so they look OK. But the photo is not brilliant.
16 colours (4 bit). Grim, huh? I once had two friends with their newish PCs stuck at this setting.
