There is no one such skin color for the latitude range you are describing.
Just look at the “average” skin color of whatever ethnicity has been in a particular environment for tens of thousands of years. Native Americans clearly have darker skin than Anglosaxons.
Also, much of western Europe has been colonized by peoples that previously spent thousands of years up further north. The weather in Britain is different from France, and so forth.
