I think we'll stay with this (the current conversion) for the time being. That might explain why the gradients aren't too much good looking depending on the virt-stuff used, or depending on the hardware, because they get rather “sharp”, which maybe could have been prevented by using a smaller color depth in the first place. But what do I know about that? ;) > A quick look at the iso boot menu or debian installer banner gradients > tells that it’s not 16 bit / 65536 colors. > > Can you confirm we don’t need to keep these restrictions so we can > update the requirements ? I'd suggest keeping those under some kind of “old requirements, not currently [$DATE] enforced” for reference, in case we need to reinstate them. Or drop them entirely (we have a revision history right?) if you feel confident enough. KiBi.
