body { background-image:url(pics/bg.png); background-repeat:repeat; background-color:#069;} 设置成这样，但背景颜色总是会覆盖在背景图片上，怎么能让背景图片在背景颜色上从而不受背景颜色影响？

你路径写错了呗。
背景图片，会覆盖背景色的，看下路径，在调试工具里，看下这个图片，是不是成功加载过来了。
图片路径不对吧

很确定背景图片已经加载了，和背景颜色叠加在一起出现了奇特的效果。
你确定加载了，那就看下，body下的第一个子元素，是不是占据整个body的，是不是你在这个子元素上面，设置了颜色。
再仔细检查下你的代码，颜色覆盖背景图片。还真是没有见过。
你把body的颜色去掉，看看会不会出背景色，就能确定，是不是背景图片被颜色覆盖了。
background：#069 url(pics/bg.png) no-repeat center center;
你的背景图片是png格式的，不要告诉我，撒是png这个你不懂
