We are located in the Pacific Northwest and want to update our office and shop. Inside our walls are tan with tan tile and the horrendous golden oak doors and trim.

Either, you can paint all the walls with light grey or white colour. Or, highlight one wall with light grey colour and rest of the walls can be white.

HP, Please share the floor plan and pics of the house. Thanks, Nitin  Cornerstone Designs Studio

When the sunlight doesn't touch the wall surface, white tends to look grey and dull. Window Walls tend to have this problem especially if none of the adjacent walls have windows. One trick to liven up the window wall is to paint it in a rich, warm yellow tone. As shown in the attached picture. But don't paint any other wall in the room in this colour, as it will be overwhelming.
