A lighter beer, without changing the recipe, can be brewed by adding some of the extract later in the boil. The technique is called, "late extract addition". LME and DME darken during the boil, Maillard Reaction. LME darkens more than DME.
Add about one pound of extract per gallon of the boil for hop oil isomerization. Add DME before LME. The remainder of the extract can be added late in the boil, or stirred in at the end of the boil, before cooling. 160°F wort will pasteurize the extract.
If you have half a jug of LME, to add late, it helps to add hot wort to it during the boil for an easier pour with less stirring to dissolve.
