Lead Test Positive? Now What?
For a house built in 1949 it would be amazing if original paint did not contain lead. The color has nothing to do with it. Most lead containing paint was white ; in the atmospheric  sulfur of an urban environment it would slightly yellow. Zinc and calcium were also used and offset the yellowing . Then when titanium came along , bright white paint with high hiding power was possible without lead.  A little lead was used but I forget the advantage it gave the paints. I would say if you don't eat the paint there is no problem , assuming you are not going to grind on the paint for hours and make fine dust. I painted the exterior of my house with a lead containing paint in 1968 and have not died yet.
