there you can see safe colors:

If i good remember IE have problem with "gold" color.
If you want rounded corners or something like:
my test forum template you can make gif images with transparent color, or other file types, but "background" in this image must be the same like on your site background.
If you are not sure that some color look the same in all browsers, you can make small gif image e.g. 9x9 pixels filled in your color. Then you can put into css style something like:
background: url(url_to_gif);
Is much more to do, but it's working.
If you use repeat and gif's width 1px then some browsers can show this not correctly - you can have diagonal lines.
-------
If you want have image only in specific place (like top of TR/TD-element) you can do something like:
<TR class="myTR">...
and in the css:
.myTR {
background: url(...) top left repeat-x;
}
you can use 'bottom left' if image must be on the bottom of element
if you want have TD-element as a "border" of other element (like in Artsu's problem, you must define in css height & width - this should be the same as size of image.
Generally:
corners: set width & height & no-repeat
top/bottom: set height & repeat-x
left/right: set width & repeat-y
-------
The best practice is, if you have most popular browsers installed in your system.
-------
If you have TD with some backgroundImage with "repeat-x"
and you want put there an image (<IMG src="yourPicture".../> tag)
and height of "yourPicture" = height of the TD
then
sometimes IE can change TD-height, even if you have "height:10px".
So better is if "yourPicture" height is less than TD-height
If not: - IE you can render this really "not good"
-------
Maybe one more thing:
- IE have problem with empty cells (TD). If you have somewhere an empty cell, then IE don't show this correctly, so you need use & nbsp; code (without space after '&')
In myBB templates it's little not comfortable, because when you use this code in one tmplate, and later you want re-edit this... myBB editor don't show code & nbsp; only normal space. So you need always remember about change this space to & nbsp;
! If you want re-edit something, MyBB editor always change all html entities
not only 'space' so be care.
I hope that this info was what you require and is usefull
