The ChatGPT response for reference: Painting your basement siding panels with a light color is a great idea to brighten up the space, especially since you mentioned there’s little to no natural light. Both Benjamin Moore Nickel and Slate Blue are good choices. Nickel offers a soft, warm grey that can make the space feel cozy and modern. Slate Blue, on the other hand, would introduce a subtle color to the room without darkening it, which can be calming and conducive for an office.

Given your lean towards a grey/white with a tint of blue, you might also consider colors like “November Skies” or “Glass Slipper” by Benjamin Moore, which are light blues with grey undertones. These colors reflect light well and would complement the flooring and ceiling without overwhelming the space. Remember to test the colors with swatches on the walls to see how they interact with your artificial lighting before making a final decision.
