This is split from bug 4762. Input boxes and some other form controls are missing the bottom underline when viewing in 8-bit colour on linux. See http://bugzilla.mozilla.org/showattachment.cgi?attach_id=8266 for a ong screenshot. Build id: 051308 Linux

This is a Gecko/HTML form control issue. Reassigning to rods@netscape.com.

So the problem here is that the light gray just gets dithered to white, right? I'm not sure there is anything we can do here without making form controls look worse in 16+ bit color...

Well, one possible solution would be to first allocate colors for form controls instead of hardcoding RGB values in layout and then the RGB color cube for other, more generic purposes... this would need a new API in gfx to obtain the color values for "light color", "shadow color", "highlight color", etc, following the implementation of AmigaOS>=2.0 (which had a very good-looking GUI interface even for 4bit screens ("only" 16 colors!!)). If anyone is interested I can come-up with a full spec what's needed to implement this correctly.

Well, right now we just say we want an "inset ThreeDFace" border. No hardcoded rgb anywhere. We get the value of ThreeDFace from gfx, then use nsCSSRendering::MakeBevelColor to create the border colors (with the last arg set to true in this case). The problem is that the resulting color depends on the background color, not just the border color... so I'm not sure what sort of simple API would do here.

One could modify Gfx to massage the CSS system colors to make them look good in 8-bit color. I think that's probably the way to go.

8-bit color doesn't seem like something we should spend time on...
