I've been playing around with the What Can I Build and really struggling with the exact color match setting so I reduced MY PARTS to two; one dk gray Door Barred (4611) and one black Door Frame (4071). Find sets to build = exclude sets, exact color match, include official sets, no MOCs, sort Highest % Match. The 1st set result contains dk gray door but yellow door frame. 2nd result has dk gray door but lt gray door frame. 3rd match matches both my parts, color and qty. Can anyone explain why I even get the first two sets when they aren't exact color matches? I would expect the 3rd match to be my 1st result. Also, when I'm looking at the parts of any result, is there a way to display the ones that are mine so that for example, when I looked at the 1st set result, I could see that of my two parts, only the dk gray door was going to be used? Appreciate anyone's help.
