Dark Muffin Pan and Yeast Rolls

Dark Muffin Pan and Yeast Rolls

Hi,  I’ve been making white rolls in dark muffin tins and have a question:  Is ovenspring stunted if I were to lower the oven temp by 25-degrees?  The other option is to raise the oven shelf up because the bottoms overbrown at 350-degrees.  But the oven spring question is still stands if anyone has some wisdom about that.  Thanks.
