If you want a light result, then quarter sawn white oak finished natural using a high quality professional waterborne polyurethane is the way to go. You will get an assortment of browns, tans and blondes in such a floor, and it still will be light overall.

Quarter sawn red oak finished the same will also give you a light result, but the floor will show mostly pink and beige tones.

Maple is nice also. Different 'grades' in that product as well, so know what you're buying to avoid disappointment.

hmm, possibly you would like the oak because of its dramatic color, matched with the rustic appearance of knots and grains which gives it the aesthetic appeal. on the other hand, maple has lighter and more natural color.

For me, maple flooring is much more descent and nice to look at.. But still the decision is yours, so good luck. One more tip, choose the one that will complement your home furnishings.
